In a phone conversation with the WI DNR yesterday I learned that there is a pilot program going on allowing SXS riding. It is done on a county by county basis meaning each county involved has their own rules. I was told to contact the counties I was interested in riding in directly. The counties are Florence, Marlinette (east side by the lake), Lincoln (midstate), Washburn and Sawyer (next counties east of Burnett which Danbury is in). The number for Washburn county is 715-635-4490. The number for Sawyer county (part of the Dead Horse trail)is 715-634-6728, Greg Peterson. Just figgered someone might be interested.
