TripHip - Travel Tips and Advice for Traveling on a Budget

Some of the best maps for route-planning can be picked up FREE from AAA offices, if you are a member. They have excellent fold-out maps on each individual state, one of the whole of the USA (great for kid's rooms as a wallchart) and others of NE, SE, NW and SW USA for planning trips.

You will need to show your membership card to get these excellent publications, but it makes the annual subscription even better value for money.
