The National (golf)

The Kemper Open was a golf tournament on the PGA Tour from 1968 to 2006. Perhaps more so than any other "regular" PGA Tour stop, the event wandered about, not just from course to course within a given metropolitan area, but along the East Coast. Originally sponsored by the Kemper Corporation, the inaugural event was played in 1968 at Pleasant Valley Country Club in Sutton, Massachusetts, before moving to the Quail Hollow Club in Charlotte, North Carolina the following year, where it stayed through 1979. (The Wells Fargo Championship is now held in Charlotte.) The event moved in 1980 to Congressional Country Club in Bethesda, Maryland, a suburb northwest of Washington, D.C., and to TPC at Avenel in 1987 in neighboring Potomac. Kemper Insurance dropped out as sponsor after the 2002 edition and was replaced by Friedman Billings Ramsey, which renamed the event the FBR Capital Open for a single year in 2003. Booz Allen Hamilton became the main sponsor in 2004, with the tournament being titled the Booz Allen Classic. The event returned to Congressional for a year in 2005 to accommodate renovations at Avenel. The purse in 2006 was $5.0 million, with $900,000 going to the winner; due to rain delays it concluded on Tuesday without a gallery. In 1992, Washington Redskins quarterback Mark Rypien, the reigning Super Bowl MVP, was given a sponsor's exemption into the tournament, but shot rounds of 80 and 91 and missed the cut by 28 strokes. As the Kemper Open, it was often played two or three weeks prior to the U.S. Open, making it a prime tune-up event; later it was either the week prior or after and many top players skipped it.. For 2007, the PGA Tour announced that it would reschedule the event for the fall, and Booz Allen declined to renew its sponsorship. The fall date was in turn canceled to make way for the new AT&T National, to take place at the same time as the Classic had. Also in 2006, the tournament ended on Tuesday due to persistent storms in the D.C. area. The conclusion of what turned out to be the final Booz Allen Classic was not televised. A new format (invitation only), new host for the tournament (Tiger Woods), and a return to Congressional Country Club marked the July 2007 stop in Washington for the FedEx Cup, the AT&T National. For record-keeping purposes, it is not a "successor" tournament officially, even though it is the "new" tour stop in the same region. During the 1970s, the Kemper Open was among the highest purses on tour, exceeding the majors.

TPC Potomac at Avenel Farm (formerly TPC Avenel) is a private golf club in the eastern United States, located in Potomac, Maryland, a suburb northwest of Washington, D.C. It was formerly a regular stop on the PGA Tour as host of the Booz Allen Classic (originally Kemper Open). After a major renovation to both clubhouse and course, the clubhouse reopened in late 2008 while the course reopened on April 28, 2009.

The Wells Fargo Championship is a professional golf tournament in North Carolina on the PGA Tour. Held in early May at the Quail Hollow Club in Charlotte (except in 2022, when it was played at TPC Potomac at Avenel Farm), it has attracted some of the top players on the tour. It debuted in 2003 as the Wachovia Championship and was known in 2009 and 2010 as the Quail Hollow Championship. In 2017, the tournament offered a $7.5 million purse with a winner's share of $1.35 million. From 2004–06 and 2011–13, the tournament ended in a playoff. Additionally, the event has one of the tougher finishes on tour with 16, 17, and 18, commonly known as the "Green Mile," often ranked among the PGA Tour's toughest holes. Organized by Champions for Education, Inc., the majority of the charitable proceeds from the tournament benefit Teach for America. In 2017, the tournament was held on the coast in Wilmington at Eagle Point Golf Club, as Quail Hollow hosted the PGA Championship in mid-August. Wilmington hosted the Azalea Open on tour in the 1950s and 1960s at the Donald Ross-designed Cape Fear Country Club; it was a tune-up event for The Masters through 1965, part of the city's Azalea Festival. In 2022, the tournament was held near Washington, D.C. at TPC Potomac at Avenel Farm in Potomac, Maryland, as Quail Hollow hosted the Presidents Cup in late September. Decades earlier, Quail Hollow hosted the PGA Tour's Kemper Open eleven times, from 1969 through 1979.

Carderock also includes a local school (Carderock Springs Elementary), Carderock Springs Swim and Tennis Club, and Congressional Country Club.Despite its proximity to the Capital Beltway, Carderock remains only moderately developed and traffic congested. This is due in part to the prominent presence of Rock Run, the Naval Surface Warfare Center, and Congressional Country Club. In addition, almost no roads running through Carderock have direct access to the Beltway. The only exceptions are River Road on the north end of the neighborhood and Clara Barton Parkway on the south end.
