Two of us making this drive (in a car) during summer '08, over 30ish days. We obviously want to take in some of the major sights/experiences, but are just as interested in the quirky, off-beaten-track stuff that might not be featured in every guide book we've already bought. All suggestions definitely considered! Also, would anyone recommend booking any of our accommodation in advance (maybe Vegas?) or could we just plan each day/night as it happens. Cheers in advance from a very excited Brit!
