Check out Badlands Off-road Park in Indiana...

I never thought I would utter the phrase "If only I lived in Indiana..." but this has to be one of the coolest ideas ever. Badlands Off-road Park has over 700 acres of Off-Road trails spanning mud, dirt, rivers and grass for motorcycles, ATVs and any Off-road utility vehicle. There is a small fee to enter but that only goes to pay for maintaining the awesome trails. There is also staff on hand to help if your ride decides to breakdown or you accidentally flip yourself over going down one of the insane inclines. Check out the website.
