In the middle of this awesome hill, you must turn 180 degrees and head in the opposite direction. (and it happens a second time, which isn't quite as severe).
John being the good sport that he is, turned around and repeated the process not once, but twice, for all of us kids to enjoy!! (we are easy to entertain!)
As a note, our 15 passenger van is probably the largest vehicle you'd want to attempt this with...our first pass, we had to stop and back up to complete the turn...good thing no traffic was coming, and thank God for good brakes.
