I suppose that you could hire some ex-marines with automatic weapons to stand guard 24/7.
Along with LoJack you would want to lock things up still. But, with LoJack vs other GPS stuff, it notifies the cops automaticly if it is stolen and has a battery back up in case the power is shut off. My wife had it on the Honda she use to have. If someone moved her bike without here near it (she had a electronic key fob thing that she needed to be within a few feet of the bike when it was moved), it would notify LoJack and call her right away.
