There's a bike locked up outside my office building that would make a perfect commuter bike for me. It's a Schwinn World Sport, in my (hard to find, large) size. A switch to upright handlebars, a rack and fenders, and I'd be good to go.

It's locked with nothing but a long cable (through wheels and frame). I could practically go through that with a garden shears. It's been there for weeks at this point. I know it never goes anywhere, because the rear wheel is nearly tacoed, and there's no way it could make a full rotation.

I don't know if the owner has abandoned the bike, or is unable to ride it, or can't come up with the bucks to fix/replace the rear wheel.

Tempting . . . but I'll try to be ethical about this. Should I leave a note?
