I keep my bike in my office and nobody has complained. However, we are moving to a new "green" building next year, and they already have told us that no bikes will be allowed inside. They are supposed to provide a secure parking area for bikes, but we'll see about that. It would be a shame if I had to quit commuting because of the parking situation, but there is not way I am leaving my bike unattended downtown, even with a good lock. I may have to start looking for more of a beater bike for commuting because my current commuter would be a tempting target for thieves.
