The Broncos are not the only game in town when it comes to inviting fans to watch their pre-season practices. The CU Buffs hold FREE open scrimmage on Saturday, August 11 from 9:30 a.m. to noon, followed immediately by post-practice selfie time on the field. Folsom Field is on the east side of the main campus at 2400 Colorado Ave., Boulder. FREE parking is available at Lot 169 off Folsom St. north of Boulder Creek. Several RTD Routes (including the FF1 from Denver wit stops along U.S. 36) pass by the campus.
