Turnberry Turn-a-Round. Start at my house... 939 12th Ave NE, through Quarry Hill Nature Center. Past RCTC. Across HWY 14. Offroad through Eastwood Park. Up Collegeview Hill. Right on Turnberry, up past the water tower. All curvy hills through the burbs to the crappy trailer park by Marion Road. Across Marion behind the Army recruiting center. Take the dirt road right to the bear creek trail. Take the River all the way back home.
