Strange, I never thought someone would think to steal a pump, but it makes sense. I'm also a grad student at a fairly large university and I have a pump that attaches to the frame. I started commuting by bike everyday in May or June, and so far the pump and my rear blinker are fine despite leaving them on the bike. I probably won't take them off anytime soon. They might get stolen, but the ones I have a cheap so it wouldn't be the end of the world. So, I guess it depends; if they get stolen, I probably will pay a little closer attention to their replacements. That being said, my much more expensive front light never stays on the bike.
