Does anyone have any experience or input on camping in our northern states? Iowa, Minnesota, North Dakota, Michigan.Great Lakes. We're thinking of hitting the road in our soon-to-be-refurbed camper in August. My reasoning is it may be cooler the further north we go (although hubby's concocting a way to install that room sized a/c in there lol). Caching, scenery, big-dog-friendly are important as,well as I suspect, a stop at Mall of America (surely there's a cache there isn't there??) Nancy
