Have you been to the Grand Canyon & Yellowstone? I have not. Therefore I MUST go, right?! My trip is all set up and you are welcome to join us. Click on this link for all the details: https://www.grouptoursite.com/charlenehatfield
There is also an available extension to Missoula & Glacier National Park, can't miss that! If you are a "single" and would like a roommate, let me know...might be able to help with that.
