Bobby Unser is a member of racing royalty, won the Indy 500 four times and has two USAC championships to his name. But in case you thought he was just a track rat, check out this footage from the 1966 Pikes Peak hillclimb posted by Road and Track. Now fully paved, Pikes Peak used to be a totally different experience.
Watching Unser crank that gigantic wheel while sliding around the dirt on those skinny tires really gives you an idea of how much different the even was back then. No safety cages, no guard rails and no pavement meant those who entered were closer to daredevils than drivers.
