michigan trail permits

[PHILIP ALLEN]

I will be in the Michigan peninsula next weekend for some exploration of the trail systems around the Mackinac area. Does anyone have information on what is required for trail permits etc. I have checked out the website but no mention of permits there. Any general info on the trail conditions would also be appreciated. I attach the website for general interest. Thanks Phil http://www.michigannorth.com/recreation/orv/index.html
