i pulled this info off our site www.atvoffroad.net
The guy who put this nicely done information together is the same guy who own's and operates www.vvmapping.com
the mapping of ORV trails for Michigan and other states.
One stop shopping for all of your county ORV ordinance info:
Current listing of each county; links to county web site; copies of county ordinance
MAPS! Maps of each county, based directly on their passed ordinance.
Includes PDF downloadable/printable maps that print on regular letter paper.
This is what I consider "late beta". There's some polishing to do on the pages (a few links to the trail maps, etc.).
If you have a copy of the ordinance for any county that I have listed as "unavailable", I'd sure appreciate a copy. I'm in process of getting copies from each county, but it's taking a while...
