i was actually on my mountain bike, because we had just got about 5 or 6 inches of snow, and it was still falling. but my girlfriend works about 8 miles away from our apartment and she only started to drive about a year and a half ago (no, she is not 17, she is 26. she lived in Philly for over 6 years and never needed a car, so she never got a license.). and i was afraid for her to drive home. it was really crappy out so i rode my bike up to her work. normally would take about a half an hour. it took me about a hour, maybe an hour 15. there is about a 1 mile up hill, pretty steep grade, so i had to walk it a few times because my tires was just spinning in the snow and slush. i was across the street from where she works and i had to cross a 5 lane express way. i had just started to peddle and BAM! i slide out on the ice and smack on my left side. didn't hurt much, it was nice and snowy, but the ice underneath did give me a good crack on my hip. i got up and laughed. i never would have made it if i took my fixed gear. i got about a block from my place and my back wheel spun out and i had to kick the bike back or take a nut shot. now that would have been funny....for everyone but me.
