1. ensure your bin has an identifying mark - say your house number
painted on, you'd soon know if the bin was stolen.

I've always wondered about this. If you put your house number on, and
your bin is still on the pavement when everyone else has taken theirs
back in, isn't it a bit of a give away that you're working late and your
house is empty and available for burgling?
