At work I always bring mine into my office. I trust the guys that work there but there are so many other people coming and going it's just safer, even if not for stealing but getting knocked over, etc. Anywhere else, I don't even lock my nice bike up, it comes in with me or I ride my old crappier bike if it's going to be locked up outside. This was a good idea since my crappy bike had its lock cut and was stolen while I was at dinner a few weeks ago. Now I really won't lock up my nice bike anywhere!!!
