Opps! That one took a couple of days to get off the dunes.
As you can see, about anything can used for fun on the dunes. Just air down to about 5 psi, get a whip flag for the front bumper, a ORV sticker, and go out and play. It's a lot of fun if you have a buddy or two with their rides. There are a lot of areas to play hide and seek in. In my YJ I spent most of the time in 4 high/1st and 2nd gears, sometimes 3rd. The bikes, 4 wheelers, and sand rails usually fly right past you. It's located on the shores of Lake Michigan, so even on the hottest summer day, breezes from the lake keep you cool. If you go, you want to be on the dunes early. It can get quite crowded,especially on holidays, and there is a limit to the number of vehicles allowed in the park at any one time.
