edit- your original question. good 2 lane all weather road.
the father wests you go on 40 the more the traffic thins out. much more to see on 40 and east than 80.
more around roosevelt and vernal local traffic.. frack sand truck run between vernal and crag but not heavy traffic. you might see 3 or 4
not a fast as 80 but quiet scenic drive most of the way.
another rout from craig and better than going north to 80 at craig.
stay on 40 through steamboat and rabbit ears pass. on the east side of rabbit ears take 14 to walden-125 to 127 turns to wyo230 at state line- woods landing then 27 mi to Laramie
when daughter was in collage we made several trips to laramie and this is our preferred rout.
less traffic and quicker than going through grandby.
over nighting possible any where, and especially form vernal on.
