Wow I started making a list of the ones that I have been to:
Las Vegas/Hoover Dam, Big Sur, Yellowstone, North GA Hill Country (lived there), Black Hills, Denver (and all of Colorado - lived there), Asheville, San Diego (now live there), Million Dollar Highway, Grand Canyon, Monument Valley AZ, Los Angeles, Seattle... I think I missed Bryce/Zion on the slides which I have also been to.
Pretty good being in the military and travelling around.
Love to do Idaho sometime soon, as well as Eastern Oregon and Washington.
