Due to responsibilities at home and unexpected expenses (new furnace this spring and transmission rebuild for Nancy's car) we confined our camping to Michigan and Ohio. Ohio has for those of us of a certain age the Golden Buckeye card which means 50% off from Sunday to Thursday at the state parks.
All of our camping this summer was in state parks and each had a 'flavor' with other campers and what they camped in.
Travers City Mi (not close to a major population center) had a range from tents to three families with almost identical large fifth wheels and two Airstreams. Most people looking fit and active. Mohican Oh (not close to a major population center has one of a very few swimming pools) lots of kids out of control on bicycles, some tents lots of big RV's fit looking people. East Harbor (near Sandusky Oh close to Toledo) Mostly large RV's (pull through sites) A lot of folks boating, Cedar Point amusement park close by, fit looking. W.J. Hays state park Mi, fairly close to Detroit, Lansing close to Michigan International Speedway (full on race weekends). few big RV's Lots of tents old small RV's and lots of very un-fit folks.
