Parked at Saguaro Park N36.02142 W114.94260 , found the trail on the north side of the park. An enjoyable ride down grade. Trail surface in fine shape. The Down 5 Trail must be a spur off to the north. I missed the turn off. The trail west of Racetrack Rd was called the Roadrunner Trail by a Park employee that I asked. May be due to the Roadrunner Park. That part of the trail meanders to both sides of the wash. Is not surfaced for a short distance where it would join the Boulder Hwy Trail. Noel Keller 24 Apr 2012
