Las Vegas Motor Speedway (track complex formerly known as Las Vegas Speedway Park from 1993 to 1996, Las Vegas Speedway in 1992, Las Vegas International Speedway from 1990 to 1992, as the Las Vegas International Speedrome from 1972 to 1990) is a 1.5 miles (2.4 km) tri-oval intermediate speedway in Las Vegas, Nevada. The track complex, since its inaugural season of racing in 1972 with off-road and drag racing, has seen expansion and has hosted various racing series, including NASCAR, IndyCar, and Champ Car. The track has been owned by Speedway Motorsports, LLC (SMI) since 1999, with Chris Powell serving as the track's general manager. It is served by Interstate 15 and Las Vegas Boulevard. The track has a capacity of approximately 80,000 as of 2023. The track's complex features numerous adjacent tracks, including a 3⁄8 mile (0.60 km) oval named The Bullring, a 1⁄2 mile (0.80 km) clay oval, and a road course with multiple layouts that is mainly used for sports car experiences for the general public. The main track also features an infield road course that is used for sports car racing. After the closure of Stardust International Raceway in 1971, plans were made to build a new road course and drag strip in North Las Vegas by Craig Road Speedway owner Curly Price on city of Las Vegas-owned land. The then-named Las Vegas Speedrome was completed in 1972, with preliminary races being held before in 1971; however, the track fell quickly into disrepair. The track was revived by drag racer Alex Rodriguez and his son for most of the 1980s. During Rodriguez's tenure, a 3⁄8 mile (0.60 km) oval was added in 1985, which is now known as The Bullring. In 1989, Richie Clyne, the director of the Imperial Palace Hotel's (now called The Linq) automobile museum, bought the complex from the city. By the mid-1990s, Clyne, Imperial Palace owner Ralph Engelstad, and Sahara Hotel owner Bill Bennett announced plans to build a 1.5 miles (2.4 km) oval on the track's complex, which was completed in 1996. In 1998, SMI and its founder Bruton Smith bought the complex.

Sunrise Mountain is located east of Las Vegas in Clark County, Nevada. Even though Sunrise Mountain is over 3.3 miles (5.3 km) NNW of higher peak Frenchman Mountain many people in the Las Vegas Valley refer to Frenchman Mountain as Sunrise Mountain since the sun rises from behind it. This confusion dates back many years and the National Geodetic Survey bench mark placed in 1947 on the summit of Frenchman Mountain is designated "Sunrise". During World War II the U.S. Army maintained an airway beacon on the summit and as of 2007, remains of the tower could still be found.Local conservationists have proposed the area, along with Gypsum Cave and Frenchman Mountain, be protected as a national monument.

Aviation Nation, sometimes referred to as America's Air Show, is the annual award-winning air show of the United States Air Force (USAF). The show is hosted at Nellis Air Force Base near Las Vegas, Nevada in November of each year. Being held at Nellis means that the USAF Thunderbirds display team usually perform at this air show at their home base as their last show of the year. Since Nellis is the leading USAF combat training center, the show is able to feature the newest Air Force aircraft like the F-22 Raptor and F-35 Lighting II. The air show is a three-day event and is open to the public for the last two days. Guests who are unable to normally access the base can park at the Las Vegas Motor Speedway and ride a free shuttle bus to the base tarmac to view aircraft static displays, tour some aircraft, visit vending booths, and watch aerial demonstrations.

Exercise Red Flag (also Red Flag – Nellis) is a two-week advanced aerial combat training exercise held several times a year by the United States Air Force. It aims to offer realistic air-combat training for military pilots and other flight crew members from the United States and allied countries.

First held on 29 November 1975, Red Flag exercises bring together aircrews from the United States Air Force (USAF), United States Navy (USN), United States Marine Corps (USMC), United States Army (USA) and numerous NATO and allied nations' air forces. Red Flag exercises are conducted under the control of the United States Air Force Warfare Center (USAFWC) at Nellis.

KDWN (720 AM) is a commercial radio station in Las Vegas, Nevada, owned and operated by Audacy, Inc., which is currently silent. The station pronounces its call letters as "K-Dawn". The station's studios are located in the unincorporated Clark County area of Spring Valley. Programming is now heard on 250-watt FM translator station K268CS at 101.5 MHz. KDWN aired a talk radio format. It ran several nationally syndicated conservative talk hosts, along with local shows, most of which are brokered programming. National hosts included Brian Kilmeade, Sean Hannity and Mark Levin. Other hours were devoted to money, health, real estate and sports. In most cases, the local hosts paid for their time on the air and were permitted to run their own advertising. Most hours on weekdays began with world and national news from Fox News Radio. A local staff provided Nevada news, weather and traffic. Weather coverage was supplied by NBC Network affiliate KSNV. KDWN's original 50,000-watt transmitter was on Galleria Drive in Henderson, and was nondirectional in the day and used three inline towers to produce a directional night signal nulled toward WGN on the same channel in Chicago. In 2020, it moved to a new site shared with KXST on North Sloan Lane in North Las Vegas. KDWN broadcast with 25,000 wats during daytime hours and 7,500 watts at night, still protecting WGN with an asymmetrical three-tower pattern. While the old nighttime signal could be heard throughout most of the Western United States, north into Canada and south into Mexico., the new signal is more economical, continuing to cover the same metro with less spent power. KDWN also broadcast using HD radio technology and is heard on the HD3 digital subchannel of co-owned KMXB in Henderson. KDWN was Southern Nevada's primary entry point station for the Emergency Alert System. KDWN, along with KXST, ceased operations on March 2, 2023.

KXST (1140 AM) was a commercial radio station licensed to North Las Vegas, Nevada, and broadcasting to the Las Vegas metropolitan area. The station was owned by Audacy, Inc. It aired a sports radio and sports betting format, primarily from the co-owned BetQL Network and the CBS Sports Radio Network. That programming continues on 98.5 KLUC-FM-HD2, also owned by Audacy. KXST's transmitter was near Nellis Air Force Base and Interstate 15, on East Tropical Parkway; the sale of the site is a factor in the station's closure. Its transmitter power output was 10,000 watts by day, using a non-directional antenna. Because AM 1140 is a clear channel frequency reserved for XEMR in Monterrey, Mexico, and WRVA in Richmond, Virginia, KXST reduced its power to 2,500 watts and used a directional antenna at night.

The Nellis Solar Power Plant is a 14-megawatt (MW) photovoltaic power station located within Nellis Air Force Base in Clark County, Nevada, northeast of Las Vegas. The power plant was inaugurated in a ceremony on December 17, 2007, with Nevada Governor Jim Gibbons activating its full operation. On average, it has since generated 32 gigawatt-hours of electricity annually and supplied more than 25% of the power used at the base.Occupying 140 acres (57 ha) of land leased from the Air Force at the northeastern corner of the base, this ground-mounted solar system employs an advanced sun tracking system, designed and deployed by SunPower. The system contains approximately 70,000 solar panels, and the peak power generation capacity of the plant is approximately 13 MWAC. This means the ratio of average to peak output, or capacity factor, of this plant is around 22%. The energy generated will support more than 12,000 military and civilians at Nellis who are responsible for Air Force advanced combat training, tactics development and operational testing. Construction began on April 23, 2007, and operation of the first 5 MW began on October 12, 2007.
