I've never been able to figure this out. First, I really do understand that if someone is set on stealing something, they can/will do it. But I'm still concerned about protecting my bike while its sitting on my trunk rack. I have pretty much the standard trunk rack, attached to the car trunk lid with straps and metal clips. If anyone wants to steal the rack all they have to do is cut the straps, which would be pretty cheap to replace. More important, the bike can be taken right along with it, or by itself. I can't see any way to secure it to the car.

Would appreciate any suggestions.
