Moped Army

Aren't there cameras on the corners up there? Chain it to one of those. Get the big Krypto lock, and a tight-fitting cover (for a scooter or whatever). Lock the cover too, at the bottom, with a little lock. If they don't see it, they probably won't try and steal it. There is much easier stuff to grab. That said, I really don't see it surviving long. Can you just leave it with your folks for 4 years???
