Someone on my local ride list posted a link to a short film showing guys
overtly stealing THEIR OWN bikes in NYC, and no one questioned them. (One
guy at end even helps!) They used hack saws, cable cutters, even a friggin'
TORCH, and the police vehicle drove right by...

If you like your bike, then never leave it out of your sight for longer than
:38 secs...
