And if you have a AAA place near you, it's also worth it. You can get maps and travel info, book trips through them, and the ones here have mini-DMVs in them even. They have occasional travel shows and other things where you get in for a discount.
The low-level membership is only good for a 3-mile tow, though. And the one time I needed them it was freezing out and they took an hour.
But it's still easier. Think of them as the Travelocity of tow companies.
