It turns out that bike theft is an opportunist endeavor. Just the way a thief might see a wallet sticking out of someone’s jacket and ‘go for it,’ these guys literally see bikes and think ‘why not?’ As a result I’ve become even more of a fan of chaining the bike to something rigid. Usually this means finding a quiet side street and parking on the sidewalk mid-block, preferably to non-opening side of a green mailbox (the kind the carriers use to store mail). If I’m going to dinner on a busy street and I find a good space between cars on the street, I’ll make do parking on the street with a disc lock. But if I’m going to work and won’t be seeing the bike for several hours, I’ll park somewhere I can chain it up.
