TENT CAMPGROUND IN WISCONSIN?

Looking for a great campsite in Wisconsin that offers tent camping, preferrably. Close lake & no electrical outlets. I'd really like to experience an actual "roughing it" camping weekend! Cooking over an open fire, set up tents & swim in a nearby lake would be GREAT!!!! So many sites now-a-days have shelter areas w/electrical outlets, swimming pools & waterpark attractions, which I'm trying to stay away from. We're planning a family trip w/children...but we're all looking forward to roughing it :). thanks alot!!!!
