Skip Barber Sells Lime Rock Park to Investment Group The new group, Lime Rock Group, LLC, will shepherd the circuit into its 65th year and beyond. DW Burnett Lime Rock Park is an institution. Opened in 1957 during a boom for American road courses, the Connecticut track has long been a home for sports-car racing here in the Northeast. A lap is just a mile-and-a-half long, but it's an eventful one, and it takes real skill to master. For the last 37 years, Skip Barber—he of eponymous racing-school fame—has owned the Lime Rock, but today, a new group of investors, Lime Rock Group, LLC, announced it has acquired the track.
