Best reference book we took (and we had Lonely Planet and Rough Guides). Gives you multiple routes, suggested offshoot day trips, down to earth summaries of towns and areas and tips to save money by eating at places with character but without big price tags. This would suit any traveller that likes to see a bit of quirky America at their own pace. No detailed maps, though, just in case you wanted a street-by-street of the towns included - it's about seeing small town America. And that's why we enjoyed it so much.
