I'm heading out this weekend on a camping trip to Tahquamenon Falls, MI, which I'm not sure I'm looking forward to...is there much to do up that way? My concern is entertaining a 4 and 6 year old for 4 days. I've been told that once you're up that far, there's nothing much around there as in places of interest other than outdoors. It's about a 5 hour drive for us. Any information/tips would be greatly appreciated! Thanks so much!
