We have about 2 weeks to see as much and experience as much as possible out West. We live in southwest Va (where VA, TN , and KY all meet). We were thinking Grand Canyon? Colorado? We'v done all East & South but not West any ideas on what can be reached in that amount of time. We will be camping/ few hotels. Any ideas would be great. We have 3 kids 5 to 12. Thank you so much.
