HELP First time in ohio/ Michigan/ indiana for camping

Hi
canadian need some recmondation for camping site. First time camping on this side of the u.s. planning to go to shinshewana flea market in indiana (looks cool) So far i am thinking of staying at shinshewana campground or pokagon s.p in angola indiana. (i was told in michigan you have to pay a extra $30 entrance fee to camp in a state park??? so a koa ect. might be cheaper? for 1 or 2 night. Is ohio/indiana the same thing???)
Any help would be appreciated thank you
