Hmmm. Places that are must visit in Ohio. Well, some would say the Rock ‘n’ Roll Hall of Fame in Cleveland. Some might say the National Museum of the United States Air Force at Wright-Patterson AFB in Dayton.

But a personal and very cool and unique one in my book is The Great Serpent Mound in Adams county east of Cincinnati.

Here is an image for those not familiar with it:

And a Wiki Page to describe it.
