NSXPO21 (NSX Club of America national meet) was near Portland in the fall of 2021 and we took a couple weeks to drive out and back.
The first major stop was Badlands National Park.From Badlands we heading west of Cody WY to spend the night. From there we took Chief Joseph Scenic Byway thru the mountains to where it meets the Beartooth Highway and from there to the northeast gate to Yellowstone National park. Just spectacular scenery the entire way.
What passes for a traffic jam in the mountains.
