I have a week off and I want to go somewhere?

Hey all! Okay so I start a new job in a week and kind of want to do something. I just got back from MN tho so don’t want to drive even more. Id love to do something camping or something but im on a pretty tight budget.

I know Indiana dunes has cool spots. Any other recommendations? Maybe just a two day kinda thing? Or less than 4 hours tbh. Let me know
