Are you a) on campus for spring and summer ‘13 and b) a responsible adult capable of not breaking things? I’m going abroad and I want to stash my bike with someone so I don’t need to haul it to storage in the next town over. You’d be welcome to use my bike (red Giant mountain bike, on the small side but very functional) during the spring and summer, and in fact, it’d be probably be good if you did, to decrease the chance that security confiscates it! And if you’re off campus for a few weeks at the beginning/end of summer, it’s no big deal—security just wants to know that someone is “in charge” of my bike so they don’t clip it. And of course, you should not let it get stolen, periodically put air in the tires, etc. Email me if you’re interested!
