Absolutely.i agree but there are loads of abandoned bikes left to rust all over the city too.
I've seen about 10 bikes rotting for the last couple of years just near my job, and one classic BMW 750cc motorbike. One of them was a lovely bike, used to be anyway.
If the bike is abandoned and rotting, leave a note on it for a month or two maybe, and then take it, do it up, and use it...
