I have a AAA Premier card. Yes, I carry some basic tools with me, but I'm not about to change out hoses, a timing gear, or a head gasket while on the road. At that point, call AAA, get a tow, and head home where I have the tools and facilities to do it properly and on my own time. Most of the time, the tow truck drivers are fascinated by the old car, so they're pretty cool to work with.
I can get a tow within 250 miles with my membership...I haven't made it that far away from my home, nor do I plan on it. But...that's me.

As they say "your mileage might vary..."
