FWIW, I just tested the theory of anyone stealing my bike without it being locked to anything.
This afternoon I had to go back to work to pick up my glasses, which I had left in the breakroom just after we closed last night, and I didn't notice until we'd set the alarm and locked the door (too late at that point). I discovered I was very hungry (after having not eaten since last night, trying to save money enough to deal with the transition from my house to the new place).
I had a coupon for Subway buy one sub and a drink and get one free, which comes out to about $9.25 if you buy the most expensive one they allow on the coupon, and each sub is about two meals for me, making that a pretty good deal. On the way home there's a Subway, so I stopped there, and just as I was turning off the bike someone walked up and we started talking about the project. It was pretty hot, especially since the front of the building faces the setting sun, so I suggested we go ahead and go inside.
Since there weren't any poles or posts I could lock up to (just pillars bigger around than my arms will reach, which is too much for my cable lock), I just locked the front wheel to the frame so it couldn't spin, took my PDA off of it, and locked the tools/etc in the lockable leftside cargo pod, then went in.
We were in there until after dark, and though as usual a LOT of people stopped to stare at it, including some highschool or early college kids on little stunt bikes that kept circling it like a pack of predators, but never actually touched it, nobody bothered it. Not even the obvious group of gang members that came thru after complete darkness set in.
It was barely within sight of the windows, but that doesn't mean much to some people (like whoever stole my bungee cords off the bike baskets of the other bike last year at Jack in the Box, when the bike was locked to the rack right outside the window I was sitting at!).
Yet, no one took it or bothered it. If it had been my regular bike, I betcha somebody would have tried, even with the wheel locked to the frame. Sometimes ugly helps. Heavy as a dead body contributes a lot too.
