COMMISSION

In the early 1960s, Aerojet General
Corporation purchased the southern portion
of what is currently the existing park to
build and test rocket engines for the federal
government. Today, you can still see both the
test rocket launch pit, and the dome-shaped
control room called the “Moon Room.” In
1972, Roy and Mary McGill leased 435
acres of the present park site from Aerojet
General Corporation and created a motorcycle riding and competition facility called McGill
Off-Highway Vehicle Park. Sacramento County purchased the area in 1975. An additional
401 acres was purchased in 1976, and in July 1988, the park was turned over to the
OHMVR Division.
