I am planning a trip with my friends from Miami all the way west to California and then back to New York and down the east coast back to Florida. I know it is going to be a long trip but I want to see as much as I can. Does anyone have any tips as to what to see besides the normal (grand canyon, mt. rushmore, etc.)?
Do you think it is possible to do this in 3 weeks?
Do you know of a site where I can plan this with stops for campgrounds and cheap hotels? (Many ask for starting and ending locations, but I am going to start and end in the same city)
Any tips, books, sites for advice?
