Travel Guide for the US?

[east_meets_west]

I'm going to be traveling extensively across the US with a new job for 9 months beginning in August, and am looking for a good guidebook to help me find interesting places to visit during my travels. Does anyone have any recommendations?

Frommer's is my favorite.  Fodor's is good.  Lonely Planet is good if you are into more backpacking-style stuff and they can have some good guides.  You will get better info if you get a separate guide for each place you go.  The All-US guides are a bit unwieldy and don't cover things in depth.

Thanks; I've been hunting around the internet myself quite a bit but was hoping to get a some more firsthand opinions. I appreciate the input....anyone else with ideas, feel free to post or PM

I personally like AAA or tripadvisor.com.

The Tiki travel guide.   Your guide for all things tiki!   It is fantastic. 
But for more practical advice I second the Lonely Planet...they are great for poor people like students.
