The garage. We have 5 bikes in the family, and it's taken some work to find room for two cars in there. I lock my mountain bike to the garage door frame, as we had two bikes stolen from the garage a few years back. Never figured out how they got in, but maybe they got lucky with a remote. I should lock the road bike too, but it's tucked way in back by the trash cans, so hopefully it won't attract much attention.
