First time I ever got a ride on a 'bike was as a passenger with my cousin. Was a young teen then, and it definitely was not cool to put arms around another guy. His 'bike was a sports bike, so not much to hold on to except the little tiny rack behind the seat. He accelerated hard when I wasn't ready and I practically rolled off the 'bike backwards... I don't recall if my feet caught under his legs or under his arms, but it scared the cr4p out of me!
I've been hooked on motorcycles ever since...
