I did a similar trip last October. We hunted north of Gillette. Left out Tuesday, early afternoon and get to Cody just after dark. Not much open then (October 20th), Covid?, seasonal?. Wednesday morning we left Cody for Yellowstone, drove the lower loop as I called it and down past the Tetons into Jackson. Left Jackson Friday morning headed back to Bama. I didn't get to see nearly enough of any of it, but I got a little taste. Enough that I know I'm going back as a tourist/fly fisherman/hunter/beer drinker in the future. It was my fist trip out that way, but it won't be my last. Had planned for September in Colorado, but have had some setbacks that have postponed that trip.

Enjoy! Soak it up! I love it up that way and have a lot more of it to see yet.
