First of all I had only planned to go the very West down to California, but by talking with my hosts, I changed my mind and my route. In addition to that I changed my route by things I was so close to, that I had to see them and take detours.
I made three tours into the USA:
1st trip = Montana – Wyoming – South Dakota – Wyoming – Montana
I was visiting the MOUNT RUSHMORE NATIONAL MEMORIAL and CRAZY HORSE MEMORIAL as well as the Yellowstone National Park
2nd trip = Washington – Oregon – California – Nevada – Arizona – California – Utah – Idaho – Montana
