I have AAA for the automotive sense of security-roadside assistance, battery jumps, keys locked in the car. Everything else is a bonus. We did save a little on our December trip...$100 maybe.
My mother insisted I get AAA when I got my license, and I still have it. It's kindof like health insurance...it's just a cost you think about cutting, but, man, if you need it...it's priceless.
