I've looked at the maps on line by the forest service. And now at 2-4 other places and the US forest service map that gives what roads are open and what type of rig can use them, it does not even show the road I would like to try. This is in Montana. The road I'm looking at even has a FS # on it. Why is it not on their road use map then?? The FS map of road use says its a 2016 version. Trying to scout a new area for this fall and trying to find access and then a trail thats closed during season to help get in a little deeper. What are some places to get a map that will show all the roads and trails and what can be used on them
