The drive on Interstate 90, especially after leaving Minneapolis/St. Paul, Minnesota gets to be somewhat boring... there's just no nice way of saying it. Across South Dakota to the Black Hills takes 4 or 5 hours of mile after mile of endless prairie broken only by your arrival at Wall Drug in Wall, SD. llike
this...
You'll enjoy the Black Hills and Mt. Rushmore, but be sure to see the
Crazy Horse monument nearby, as seen
here.
Then across northern Wyoming, take time to see Devil's Tower near Sundance, Wyoming ...
thus...
If you actually stay on I-90, you'll miss Yellowstone National Park since the best entrance from your direction will be through Cody, Wyoming, which has the finest western museum in the world
here... You can go out the north entrance near Bozeman, Montana and pick up I-90 again.
After that, although having been through the area many times (we live in the western U.S.) you-re on your own. Seattle is several days of many things to do, including a ferry ride across the Straits of Juan de Fuqua, as seen
here...
You'll be interested in hearing that gasoline is now less than$2.00 a U.S. gallon and expected to continue to drop.
Enjoy!
