I want to try to get together with my cousin and her two little girls this summer (6 and 3). I'm in Harrisburg and she's in Green Bay so we'd like to find a half-way point that we could meet and spend the weekend. I'm assuming that would be somewhere in OH (probably western, by the MI border maybe?). Can you guys think of of somewhere where there's stuff we could do with the kids and still relax and catch up (and, of course, not spend a TON of money)? Thanks!
