Not good. Having hunted those areas, these roads are critical to get to some of the places. I suspect some of this is from the experience about five years back when a big winter storm came and tons of ill-prepared hunters were stuck. I suspect I could chain up and get to most of those areas, pending how many trees might fall across the roads.
Seems a better response might have been an email to every tagholder in those areas, "We are advising you of a significant winter storm forecast for the area of your elk tag. Be advised, the USFS does not, and will not be able to, provide rescue services to those who are not prepared. Be advised that you should be prepared for terrible conditions and being stranded for significant periods of time."
The new travel management plans already have created some strained relationships with locals. This will surely do nothing to help that situation.
