I'm planning to take a trip to the Turtle Ridge ORV Park on Drummond Island in the U.P. of MI. (http://www.turtleridgeorv.com/) Has anyone been there? How is it? It looks pretty sweet. I guess it's 400 acres strictly for "off-road" vehicles. I just haven't heard from anyone who's actually been there to comment on it. Any comments would be great.
