According to my plan, we shall enter the Southeast corner of the state and travel counter-clockwise to visit

• Cheyenne
• Casper
• Devils Tower National Monument
• Fort Phil Kearny State Historic Site
• Sheridan
• Flaming Gorge National Recreation Area
• Cody
• Yellowstone, Yellowstone, Yellowstone
• Grand Teton National Park
• Fossil Butte National Monument
• Bighorn Canyon National Recreation Area
• Laramie
• Cheyenne

There's a bunch of Denver days in front of this list and another day at the end, since that's where we're flying to and from. Now that I have the list recorded here it will be interesting to see how close we come to visiting all these spots.
