I've just started hauling the front wheel around with me. I figure, if they're going to take the bike, they're going to have to carry it, then go find another wheel, or at least go and jack someone else's front wheel. Just as long as I can make 'em work for my piece o' crap beater. And plus, I was getting sick of dealing with the U-lock AND the krypto-cable. Too much crap and work IMO.
