hehe, I have some mace in my car, and my friend sprayed some just to see how far it went, and the wind blew it right back in the car. Let me tell you, AVOID being hit by some mace if you can at all. Its VERY unpleasant.

For self defense, a taser would be much better, as it completely makes any assailants limp and useless, as to where mace might anger and enrage cartain bearish attackers. Get the kind of tazer that shoots the barbs out. If you can over there, I don't really know....
