I was wondering how late some of the major forest roads are passible in the fall. My wife has a hunt in November off of paved roads that are maintained so I'm not worried about that,but I was thinking about going out the week before on a leftover cow tag. I called the forest service to ask if a certain road would be passible with my horse trailer. She said probably not but then she gave me ALOT of mixed information that left me confused and wondering if she understood my question. I realize that snow is possible anytime from Sept on but as a general rule when does it get to be a problem? This is western Wyoming. On the eastern edge of the wy range.
