I watched the girls on the bikes.....dammit.....my best friend and I knew we could go places with the stunting we did on our bikes(not the sitting on each other part). Our mothers ruined it for us by continually yelling at us to stop doing that stuff. Then they followed through by telling our fathers who grounded us and took the bikes for two weeks!
When we were about fourteen we had 26" touring bicycles(he had a single speed and mine was a three speed) that we would stand up and wheelie side by side for half a mile at a time(until his mom caught us). Damn that was a long time ago.
