What's the quickest way to get to Big Sandy from the east side of the range? I know somewhere west of South Pass I've driven past a sign for the "Muddy Speedway" or something like that that seems like it might save some time rather than heading all the way to 191... anyone care to comment?
When heading west on 28 (from Lander) after you cross the Sweetwater River, about a mile later there is a turn off to the north ("Muddy Speedway"). Take that. Follow signs.
