To steal, also to rob without mercy, pretty much anything can be jump-jacked, basically the limit is a rocket ship, the U.S.S. constitution was known to be jump-jacked from the harbor by four kids on a field trip to Salem, Ma.(It was so badass) Although, people who jump-jacked from the general store were very lame and felt the wrath of THE RICK G.Usual spots for jump-jacking include Dick's and people's gym lockers.
