East Coast Roadtrip

[BB&J]

I'm trying to plan ahead because I want my trip to be perfect. My boyfriend and I are planning to take about a month during the late summer or fall, and drive up the east coast from Louisiana. We have a whole month and money won't be too much of an issue considering that we plan on sleeping in the car and camping out for most of the nights, if possible. We're both 22, so age isn't an issue when it comes to finding things to do. We'll be spending a good bit of money on gas, considering we're trying to make it up to New York to see his family. I'd like to find a drive-in movie theater because I've never been to one. We'll need to find beaches that we'll be able to camp out on without having to pay. (Are there beaches like that?) I'm really into art and museums, so I would like to try and visit a few on the way! Any help would be appreciated. I'd like to have a little bit of planning done, though I do have a whole year to think about it!
