Any issues in Yellowstone National Park? Going in June from WA. MT does accept my CPL.
If you head out of the park east or south in WY and it isn't too bad. It's only about 1.5 hours from W. Yellowstone to Jackson. In the 3 times I've been to the park, I have not seen one person OC.
Protip: If looking for wildlife, tour the park late afternoon and dusk. Around the Roosevelt cutoff to the north/nw exit. Grizzly was rootin' for food. Then coming back we looped around Tower Falls and Mt. Washburn. Coming around a hairpin at the top of the pass we saw another Griz walking along the road. Plus the roads are pretty empty.
