I always carry a large pocket knife with me, in my pick up I carry a 24" extendable batton and a large tear gas bear repellent ..... attached to the back of my seat a 9 mill carabine with a 28 shot clip, I have the back of the seat covered so that it looks like part of the back seat.

Also carry my 3 days back pack an in winter a heavy sleeping bag.
