Oh man, too many to choose from.

26 from Dubois WY into the Tetons, south at Moran to Jackson or north into Yellowstone, all of the two lanes are beautiful around there.

89 from White Sulphur Springs up to Riceville MT is beautiful and way off the beaten track.

Going to the Sun Hwy in Glacier Nat'l Park then hopping over to 17 into Waterton in southern Alberta is amazing.

Biggest challenge I've driven between beauty and skill, US 12 from Lolo MT to Kooskia ID. Take the route used by Lewis and Clark on their westward journey to the coast. 134 two lane miles full of turns, beautiful scenery, mountain streams and just fun managing the twisties.

CO12 from just west of Walsenberg around to Trinidad is a beautiful valley run.

I did CO17 from Antonito CO to Chama NM with my Dad a couple of weeks ago. Two beautiful passes, a vintage steam train and a C-130 doing a low low level, what an experience.

160 out of Pagosa Springs over Wolf Creek Pass is a great jaunt. You could have one helluva 3 day weekend driving around southwestern Colorado, there are no bad two lane roads there.

550 from Durango to Silverton then over to Ouray CO is really gorgeous. Finish it off by taking CO62 then CO145 into Telluride, a little touristy but in a beautiful valley.
