Rushmore is neat, Teddy Roosevelt was very neat as well as is Devil's Tower. Might be hard to work in see both Roosevelt & Tower....so far apart and Roosevelt would be taking you away from Yellowstone. I believe Little Bighorn Battlefield Nat'l Monument, MT will be on the way to Yellowstone as well.

In Cody try to see the Buffalo Bill Historical Center with Five Museums Under One Roof.
http://www.bbhc.org/museums/index.cfm These 4 were really great:
Buffalo Bill Museum
Whitney Gallery of Western Art
Plains Indian Museum
Cody Firearms Museum
North of Cody is the town of Powell which has a free campground at Homesteaders Park. The park was clean, safe and friendly. Dump services are free. Watch out for the lawn sprinklers, they will also water the parking area (soaking your unit).

I had to hold granny in gear and ask my wife to manually apply the trailer brakes now and then. They had a sign warning of the steep down grade, I should have taken the fork to Shell/Greybull. Most of the route was neat, all very pretty execpt for the 14 miles with 10% grade and sharp curves which I am sure was also pretty but I was to occupied to really notice the scenery.
http://www.rockymountainroads.com/us-014alt_wy.htmlIf you need a campground in Bismarck or Mandan, North Dakota and if you can get into General Sibley Park my son said it was really nice, but was filled up when they were there.
http://www.bisparks.org/Facilities/sibley.aspThey stayed at a small place in Mandan. In 2008. Colonial Motel & Campgrounds 4631 Memorial Hwy, Mandan - (701) 663-9824 We had passed by it in 2007. It is in an commerical area, not very resort like from the entrance off Memorial Hwy, however later on we rode by the back side on a bike path and it looked good. As it turned out it had water, electric and sewer hookup for $19. The bike path leads accross the river and by the zoo and a nice park.
From the web site Gen. Sibley is $20 with water and electric but the setting is much better. Closer to the river. Both have trees. At Colonial the sites are very close together. Sibley they are space out. Sibley has over 100, Colonial maybe 20. It did not fill up while my son was there.

4480 Fort Lincoln Rd
Mandan, ND 58554
(701) 667-6340
http://maps.google.com/maps?sourceid=navcl...1&ct=resulthttp://www.fortlincoln.com/In July of 2007, we stayed at the KOA Bismarck, over priced and dusty. We had passed the Colonial campground but it did not look very inviting from the entrance, but seemed OK from the back. Not a bad price with water, electric and sewer for $19.
