Tell us about when you realized that riding on two wheeled objects with pedals (nooooooooooo this is not *ahem* cycling related.....) was something that you'd really get into.
I wrote an essay about it somewhere here on Foo but I can't find it now.
edit: It was in the essay contest but that thread has disappeared, even though I searched. Perhaps a mod will be able to pull it out of the archives for me? I should have kept a copy.
