The Drumheller Demolition Derby Club has been tweaking the track for months, and now they are ready to roll. Hidden Valley Motorsports Park, located one exit east of Wal-Mart opens on May 27th for its second season. Following a wildly successful inaugural season, this year is already shaping up to be even better; more events, more races, tougher trucks and faster cars. Saturday, May 27th promises something for everyone this year. The season opening event includes demo derbies, stock car races, mud boggers, claimer cars and some Highriders.
