Figure a budget. Figure expenses for gas, food lodging and play money. I always figure my gas expenses based on 300 miles per tank and divide the total trip mileage by that. You can go to map quest and figure mileage from point to point. make sure you figure in some extra for taking a side trip or two. Go to www.gasbuddy.com and you can get real time gas prices around the country. Figure 25 bucks a day for food per person if you are careful. You can get motel rooms for around 45 to 65 bucks a night if you are frugal, or take sleeping bags and camp along the for a lot less.
Maybe 300-800 Good luck =DBut you didn t say how many days you were thinking of going for?It should be based on the amout of daysMore days=More Money
