100% on what Dana said. I used to live in the same area he does, except south of Jackson down in Star Valley. I don't have the route in the memory bank right off hand, but you can drive from the Pinedale area down to I-80 on all FS roads. I did it a couple of times and would always find something new or interesting. I MIGHT have the route stashed somewhere and will shoot it to you if I can find it. If not, you can easily piece it together from FS MVUM Bridger-Teton online maps. The roads were generally good, but if you try it before about mid-July, you might hit some mud, washouts or downed trees, so bring a chainsaw as the FS might not have gotten around to checking them all yet and making repairs. If the winter was fairly mild, then most of the snow should be gone with the exception of a couple of the higher passes, which still shouldn't be too difficult.
Depending on what we end up actually being able to do next spring, ie: being able to go to Baja or not (COVID dependent), going back to and through WyHoming is one of my alternate plans after Expo and Death Valley. MAN, I miss living up there....
