Why not drop in at

Have a beer at the Silver Dollar Bar in Jackson Hole.
Shoot the rafters going down the river, too.
The Wind River Canyon - South/East from Yellowstone towards Lander, WY
Don't miss the Wind River Trading Post just out of the Canyon.

There are only two seasons in Wyoming:
Snow, and Road Construction.
Snow is 8-9 months long.
Road construction is ALL the time there isn't snow. It isn't really construction. They put down a thick layer of road tar, and spread pea gravel over it.
Then the tourist traffic (You) drive over it, after waiting 30 minutes for the pilot car, to pack the gravel into the tar.
While waiting, you can look over the scenery. When traveling though, often the scenery is the back of a lumbering RV ahead of you.
Old Faithful isn't anymore. When Mount Saint Helen's popped, it screwed up Old Faithful. Now it kind of goes randomly. So have a seat and relax outside the general store and wait in the shade. Remember, you can get closer with a zoom instead of standing in the sun. Which is hot in the summertime there.
Insect repellent with DEET, and shady hats and long sleeves recommended.
If you want to avoid the crowds, see Wyoming in the snow time.
Have a good trip!
