It seems like I see at least one bike locked to a handrail outside a building every day. Alas, it looks like this is no longer a viable option. From an all-campus e-mail:
Due to the adverse impact on fire egress and building accessibility, bicycles that impede entrance to or exit from buildings (including handrails and ramps) may have their locks cut and will be confiscated by Physical Plant. Bicycles that are not claimed by the next semester will be donated.
If you find that your bicycle has been removed, please contact Jeff Miller of Physical Plant at 860-685-2568.
I like how the bikes will definitely be confiscated by Physical Plant, but only may have their locks cut. Maybe bikes with handrails attached fetch more on the black market.
