I'm a firm believer in Roadside America Roadside America - Guide to Uniquely Odd Tourist Attractions
You can search by route, state, or theme, for things to tickle your brain or your funny bone.
Would NEVER have found Fish Head Park in Michigan without Roadside America! Now, I need to make a trip to see the "Naughty Cows" in the UP!
So MUCH to see, so little time!
