The third day of my 1990 summer vacation begins as I leave Estes Park, Colorado via Big Thompson Canyon. That is followed by a stop in Loveland for breakfast. I then spend some time in Cheyenne, Wyoming, where I visit the State Capitol and see part of the Frontier Days Air Show. I then drive west on Interstate 80 stopping at the Summit Rest Area and Rollings on the way. I end the day in Rock Springs, Wyoming.
