We also got back from a 6000 mile vaca.
Yellowstone, Bad Lands, Black Hills are a wonder to see and well worth the trip.
Deadwood: Looked like there was slot machines in the front windows
of most of the places on main street.
South Dakota, Wyoming, Montana, Colorado, Kansas: we both can say, we never saw so much of nothing in our life. Nothing as far as the eye can see. No wonder you can buy so many acres in Wyoming for little to nothing compared to land in the East. Sure would hate to drive home from town only to be reminded that I forgot the milk.
