route feedback from Grand Tetons (WY) to Columbus (OH)

Hey ya'll! I am going to be attempting a trans-am (very soon) and am fine tuning my route. I would love any feedback on this large section if anybody has the chance/knows any of these areas well (especially eastern WY and SD sections).

Any spot checks are greatly appreciated. This subreddit has always been an awesome resource!!
