Tips for traveling from Va to AZ-NM north to Yellowstone.

Thank you Renee G. I didn't look at a map before posting just knew I anted to see the Grand Canyon and needed to visit my brother in Silver City. My son just moved to Mountain Home Idaho, from Florida, and we are planning on camping with them for Memorial weekend. we will try and stay at Craters of the Moon campground. My son has a pop up so any other suggestions for them would be great. hanks again,
Connie
