On our campus we have two bike racks- one out front by a very busy highway with a security guard and another out back closer to the shower.

The one near the highway is undesirable because any opportunist can see my bike out there and get to messing with it. Although there is a security guard in the adjacent building, sometimes the windows fog up and I doubt if he even looks out towards the bike rack anyway.

The one out back is far away from any street but is not monitored by a security guard. It's right in front of a fairly busy building, though, I don't know if any of the other students would have the sand to stop someone messing with my bike. I wouldn't expect them to.

What do you guys say?
