Wow, suddenly Idaho Falls is a lot farther from Jackson (about an hour in summer conditions).
Exactly. I normally travel from Pocatello to IF, then up SR20 to the west entrance to Yellowstone National Park. Most of the time, the return trip home is just the reverse. Less often, the route goes south through Grand Teton National Park. Upon arrival at Jackson, there is an option to take the more difficult, but shorter SR22 over Teton Pass or the long way down SR26. Now that the option is off the table, the trips south through Jackson will happen less often.
