...take an abandoned bicycle?
Theres an old (circa2000 steel and rusty) trek mtb which has been left leaning unlocked on the racks near my workplace for the last seven days at least.
The seatpost and saddle have already been taken, the grips cables and one pedal is missing and whats left is pretty knacked.
I have a garage full of old bike bits and would repair the bike and use it to commute.
Whats the legal and moral best way to proceed?
