Here in Ohio, state government officials brag about Ohio's system of state parks being one (1) of the best in the land. They are rather nice. There are some wild and rugged state parks, some historic state parks, some parks with big Lake Erie beaches, some parks that are actually state-run resorts (golf, mini-convention centers, etc.), some parks that focus on water recreation in damned reservoirs, somre parks that have some really nice hiking trails, and some parks with nice campgrounds.
The state park at South Bass Island is pretty, a good place to camp if you are visiting Put-In-Bay (fishing village with a drinking problem). A relaxing little park west of metro Toledo is called Harrison Lake. It has a small lake and a campground that fills every weekend with folks who just want to sit around a campfire and take it easy.
Some of the parks in west central Ohio became hotbeds of youth "carrying on" back in the 1960's and 1970's......party! During the 1970's and 1980's this Bear camped in many of the Ohio state parks located in southeastern Ohio. All in all, Ohio's system seems well-kept, reasonably-priced (such as for camping), and somewhat evenly-distributed across the state.
Michigan's state parks are pretty nice. Some of the Upper Peninsula state parks are huge tracts of wilderness, which I tend to like. Many Michigan state parks are located on a Great Lake, giving the system some of the best fresh-water beaches in the world. Michigan's state park campgrounds, though, tend to be plotted with maximum camp units in mind.....making for some pretty small sites. In the far north of Michigan, state camp land is almost always adjacent to National Forests or State Forests. Campgrounds at those places, altdhough more primitive, are a whole lot nicer because of camp unit sizing.
This Bear has also camped in state parks in Indiana, Illinois, Pennsylvania, Massachusets, New Jersey, Tennessee, Minnesota, and Oregon. The state parks I camped at in Oregon were amazing......
What say you? State parks in your area any good? In your travels, state park systems nice?
