The Planning Continues

After a several suggestions from friends, I've updated my list:

Google Map of Locations

Austin, TX
Carlsbad Caverns, NM
Grand Canyon (South rim), AZ
Bryce Canyon, UT
Zion National Park, UT
Yosemite, CA
San Francisco, CA (?)
Crater Lake, OR
Cannon Beach, OR
Mt. St. Helens, WA
Mt. Rainier, WA
Seattle, WA
Glacier National Park, MT
Yellowstone, WY
Grand Teton National Park, WY
Arches National Park, UT
Denver, CO (?)

I'm still trying to figure out what to do after Arches National Park. I'm thinking Denver but that's not set in stone.
