For those of you that park on campus do you have to have a parking pass? I just picked one up and we are required to adhere this 2"x2" sticker to our bikes. If I still had the huge ass mudflap on the back of the bike i'd put it there. But since I cut that off I think the only of place to stick it would be the chain guard or the rear tire hugger. Does anyone else have any ideas where to stick it? Where would you put it?
