Roadtrip Problems!!!

[Waratah]

Hi!

Myself and girlfriend are planning an east to west trip across the US but on a budget. We are flying into Atlanta (for a counting crows gig!) in september and have till late november to get to San Francisco. Our budget seems alot ($10,000) but this works out at $119 per day and we are a bit worried this might not be enough! Regarding accomodation, we hope to spend about 70% in motels, 30 % camping plus the odd night at family/friends houses and we are not too worried about sourcing cheap food. i really wanted to spend the whole trip with the freedom of a car but after researching prices we have resigned ourselves to a 30 day rail pass to cover the eastern states (to chicago)...we then hope to rent an economy vehicle and travel historic route 66 (budget permitting!) but it just seems so expensive...especially as its a one way hire. We would really appreciate any advice, info or tips at all about cost of trippin' over the pond. we did consider buying a vehicle but this could be more hassle then freedom i think!

Just wanted to say also this site is sooo helpful when planning a trip!

Many Thanks
