<human>: Give me the gist of the text in a nutshell

I go to Coastal Carolina in Conway, SC. I'm done with finals but I can't go home yet because there are guests sleeping in my bed. They'll be gone Thursday. Instead of sitting around on my ass for two days, I want to go somewhere and experience something.   
So I have two days to drive somewhere within a reasonable distance and go do something (preferably something very, very cheap or free).  Keep in mind that I've experienced most of the exciting things in South Carolina after living here all of my life. Think eastern Georgia, southern North Carolina. Any ideas from you guys?   
Also, how safe is it to sleep in my car in a parking lot of a Walmart or something similarly well lit and busy?
<bot>: I have two days to road trip within the eastern GA, southern NC area. What cool, free things are there to do in one of those two areas?
