Mine resides in the server room at my work. Only once has anyone ever moved it, and they regretted it. (I messed with them for a week, randomly either shutting off their internet access altogether, or just removing access to their favorite non-work related sites. Yes, I'm an evil li'l bastage. *cackles* )

Thanks for all the good replies, everyone. Lots of good ideas. Bike lockers are a great way to go. I'm going to try to convince my employer to install them. Wish me luck!!

No, no safe place for bikes. Just a half covered area on a part of the loading dock that trucks can't reach. The 3 or 4 of us that ride out of 95 to 100 workers lock to one side of a railing with a wheelchair ramp on the other. Only good point is that most of the others do not even lock up their K-mart MTB specials. One guy has a light cable lock. I have a good U-bolt and lock frame and rear wheel. I'd be the last one stolen., maybe. My bike is worth three times the others put together so I will be upgrading my security tomorrow. When the rains stop I will leave my old beater truck there and put the bike inside, locked to the steering column.
