For defense against various types of people, what do you guys put under the seat or in the back to help defend yourself and your car? On advice of my good friend I'm going with the 26" expandable ASP baton. It has a weighted tip and a guaranteed locking system. Plus 26" of pure steel is a pretty good deterrent if any uppity ricers start eyeing your car at a gas station after beating them at the light, eh? What do you guys use?
