We just got back from a trip to the NL - we camped from Thursday to Tuesday in the Platte River Campground. Great sites, great facilities, and it's in a beautiful area of the state. We brought the kayaks and paddled the Platte and Betsie Rivers - the Platte was crowded with families and had a bit of a party atmosphere, while the Betsie was very quiet and plenty of wildlife along the way. We were there about 7 years ago and have talked about getting back - I'd recommend the area highly. There's a ton to see and do all along the Lake Michigan/Traverse Bay coast - it's about a 6 hour drive north from Chicago.
