Hi there, me and a friend are currently planning a big road trip of the USA for his 21st birthday in March 2010. We're situated in the UK by the way. Basically, we've hatched a plan to fly into Newark and do a big round trip of the states, getting to the west coast and back ideally within a month, and seeing a good proportion of the states in the process. Now i've been to the states numerous times, and know exactly what to expect in terms of food, the road system etc etc, but what i'm really looking for is some help in getting the best route and the best "sightseeing for mileage" i can. I've looked into flights and the cost of car hire (looking at about $1000 total for the car and around $500 each for the flights) but need a bit of help on how much i can be expecting to spend on various other things. I figured a rough estimate of £1000 per person ($1700ish) should suffice, but i really don't know. If anybody with a bit of experience in road tripping this fantastic country could give me some guidance on what sort of non-obvious expenses i'd be looking at would be amazing. Thanks a lot
