I just had 4 bikes taken from my garage (condo complex, shared garage, but secured.) I'm pretty paranoid when it comes to locking up out on the street, but was not too worried about it at home. I live in a small building in which most of the residents haven't changed in years. There isn't really a good way to lock up bikes at the front of my parking spaces where I have to keep em. I had been toying with a few ideas, but hadn't done anything about it yet.

Makes me wish I had taken the cost of one of the bikes stolen and spent it on locks instead. Although I'm still not sure what I would have locked them to, aside from each other which doesn't seem like much protection against thieves driving around with a van.

Has anyone dealt with that kind of situation? Would a PVC bike rack filled with concrete do the trick? that's about all I can think of that I can get away with w/o drilling into the walls to sink attachment points, something I doubt would go over well.
