Auto Racing is revving its engines with the recent addition of Edmonton to the circuit. The Grand Prix of Edmonton, part of the Champ Car World Series, is a top drawing card. In its inaugural year in 2005, Edmonton set the attendance record with 200,052 spectators. Castrol Raceway (Rte. 19, 2 km west of Hwy. 2 S, on way to Devon. 780/461-5801. www.castrolraceway.com), a multiuse motor-sports complex, has events most weekends from May through October.
