Didn't say when.
My suggestion at this time, is to avoid 191 up from the south of Jackson. If you come up through Riverton and Dubois to Moran junction it is a fantastic route with the windriver range to the south. I don't remember any serious climbs, but I pull a popup behind a truck so I might not notice them.
Also recommend checking forest fire data to see if any are in the immediate area and roads are close.
