we have ****loads of bikes here, many left abandoned by students.
all it takes is a drunk ******* to come along and stomp one of those aluminum rims, and the owner will let a $300 Trek, Fisher, Giant, whatever-- rot eternally. They can't use it to get around anymore, so it stays locked through winter. Spring comes and they've totally forgotten about where they left their bike. They go home for the summer and put it out of their minds for good.
They don't know that it'd cost $40 for a shop to replace the whole wheel, and no more than a couple of minutes. But, alas, their parents bought the bike in the first place, so they don't care.
I just know damn sure what I'm taking isn't wanted.
