Thanks for the sights to see - I have added them to the list! We like historical stuff for sure!I enjoyed Hwy 28 in Wyoming over SouthPass.. This is the "Pass" the mountain men discovered and was a main road on the Oregon trail... Very remote .. All along the way you can see the Lesser known marked sites of the Oregon trail.
I have been north and south of it, but the Guernsey Ruts in eastern Wyoming are on my bucket list... Solid rock carved down by the wagon wheels...
Out of Cheyenne, Wy are remnants of the original Trans Continental rail way... No longer used roads built and a large railway trestle.. amazing what was accomplished.
The black hills area is very touristy, in my opinion... TOO CROWDED
So much to see in the USA.........
Much appreciated!
