A lot of people would think that speeding through the woods or up a single lane road at breakneck speed with no little thought for personal safety or vehicle well being not to be the best of ideas. I might agree.
But I don't think that even I would hazard to attempt what this guy in the sidecar is doing. Not only along for whatever ride the driver happens to come up with, but they are also a very active part of keeping the vehicle on the ground and cornering well with no protection whatsoever. The closest thing I can think of this this sporting endeavor is that of your old school barnstorming wingwalker.
This was from the Ascutney Hillclimb here in New Hampshire this past weekend.
