Hwy 16 is a great road too IMO. In fact, I kinda think 16 a longer scenic ride than 14A or 14. How about you?
Hwy 16 is always a great ride, I usually ride 16 east to west, 14 west to east to Dayton , 14 back to Burgess Junction and then 14 A west to Lovell. This year I camped in Greybull for a couple of nights and rode all of the above in both directions.
I then camped in Yellowstone for 4 nights to do a little Trout Fishing along with some riding, I learned long ago that you just don't pass up the Beartooth or Chief Joseph when in the area.
