I have had AAA since I started driving in 1986. My dd, when she got her first car had the intelligence to immediately purchase AAA although its taken about 5 years to convince my DH's kids that its a worthwhile investment.
Unless you live in a congested area, you need the 100 mile towing plan (when i lived in NYC, i got by with the lower, but when I moved to VA, I upped it and added DH as a second card holder)
I forget to use it for other discounts, but whenever we start talking about trips, I go onto the site and order street maps from the area....FREE
Maps of locations not around you are hard to find otherwise!!!
