Tallon Early, a plumber from Fargo, N.D., checks the tire pressure on his 2012 Honda Civic Si before the Autocross event held Sept. 14, 2014, at the free zone in front of the 3-Bay Hangar on Grand Forks Air Force Base, N.D. Nearly 60 entrants driving cars of every make and model participated in the day-long event, with proceeds going to benefit the Wounded Warrior Project. (U.S. Air Force photo/Staff Sgt. Susan L. Davis)
