Interesting (to me) post about bikes managing abandoned at college campuses and bikes left on city bus:

Not about bikes, but my favorite part of this post:
The most common items {left on buses** are black umbrellas and black gloves. Bus drivers get first claim on anything that is never picked up. Steffen told me that some like to hold on to surplus umbrellas; some drivers hand them out during rainstorms.
