Thanks again for all of you information. I have adjusted my route from Cody. I will take 14 to Greybull then 16 to Worland, Ten Sleep and Buffalo. Sheridan was not a destination stop, just a stop-over night. We will stay in Buffalo instead. From Buffalo we will take I-90 to Rapid City. We plan to stay at Rushmore Shadows RV Park. The park has some good reviews.
The rest of the trip headed back Florida will be simple. We are going to the Wisconsin Dells. We haven't been there in 25 years. Then we are going to swing south and visit our old neighborhood in Westmont, IL then head to Indiana Dunes SP. As long as we are in Indiana, we might as well head to Elkhart and take the factory tour where our coach was built. We will leave Indiana on I-65 to Nashville, where we will probably spend a few days. After Nashville, we need to get back into reality mode because our trip will almost be over.
