Next Summer after I graduate from college I am planning to take a cross country road trip. Seeing the must-see places, but also want to hit local favorites and chill places. I'll pretty much be doing a perimeter run of the country; starting in Virginia Beach, going down to FL panhandle and then across, up Cali and then kinda diagonally down from Seattle til the Mississippi-ish where I'll keep going south 'til Tennessee where I'll make my way back east to Virginia Beach.
The main things I need help on are financing questions, and if there are any specific route/attraction suggestions for the basic path I just described.
I've figured about $800 for gas would work? and I am VERY frugal. I live on practically nothing now, and to say the least I'm pretty much just a bum, ie: I don't need nice places to sleep or fancy food to keep me happy. The open road and a great experience would be enough to fuel me, I think. I hope to couchsurf and camp. I have about 3 months for the trip. Or whenever, So I can take my time and stay places for however long.
Basically I'm wondering how much money is needed approximately to eat for 2-3 months, cheaply, but to not starve, and what other expenses should I tally in?
I will be with friends for a few legs, and by myself for some as well.
(sidenote: I will be receiving a new car around graduation from my parents [they're nice people, i know] so it shouldn't have too many miles on it and it will obviously be in new condition.)
Thanks for the advice!
