Motosports Park is a motocross facility near Byron, Illinois, United States. Founded by Joe Vincer in 1969, MSP (as it came to be known) caught on almost immediately in the Midwest motorcycle community. Now run by Joe's son Aaron, MSP is home to about 35 motocross and ATV events annually, including the ten-part Nuclear Series, an American Historic Racing Motorcycle Association (AHRMA) Regional race, the first leg of the Racer X Senior Series, frequent American Motorcyclist Association (AMA) Regional and National Qualifiers, and occasionally the Illinois District 17 State Championships. It is located in Rockvale Township in Ogle County, Illinois, just southwest of Byron. The Nuclear Series is named after the two huge nuclear power plant towers, part of the Byron Nuclear Generating Station, that loom ominously over the park. The power plant was built after MSP was. A large attraction to MSP is the final round of the Nuclear Series, which concludes with a pig roast, awards ceremony and parties in the pits. In 2004 Aaron Vincer announced that he was building another track on the grounds of Motosports Park, which (named by his mother, Sue Hachmeister) became known as the Hilltop Track (and consequently the original track became known as the Legacy Track). Hilltop is now home to the 50cc, 65cc junior and beginner, and all ATV classes. Legacy remains home to the 65cc senior, 85cc, 125cc, 250cc and age division classes.

The Byron Nuclear Generating Station is a nuclear power plant located in Ogle County, Illinois, 2 miles (3.2 km) east of the Rock River. The reactor buildings were constructed by Commonwealth Edison and house two Westinghouse Four-Loop pressurized water reactors, Unit 1 and Unit 2, which first began operation in September 1985 and August 1987 respectively. The plant is currently owned and operated by Constellation Energy. The plant provides electricity to northern Illinois and the city of Chicago. In 2005 it generated on average about 2,450 MWe, enough power to supply about 2 million average American homes. The station employs over 600 people, mostly from Ogle and Winnebago counties, and features two prominent 495-foot (151 m) cooling towers. The Byron plant has been subject to some controversy with respect to a lawsuit in 1981 with concerns over tritium contamination in groundwater. Tritium contamination at Byron and other Illinois nuclear power plants led the state of Illinois to pass legislation requiring plants to report such contamination to the state within 24 hours.
