I want to take my kids to see Mesa Verde and possibly Grand Canyon on the way if we have time. We would be going July 15 and need to be home by the 21st in the evening. We live in Concord Ca. Just wondering the best driving route to get there or we might be able to fly to AZ or Las Vegas possibly. Just wondering if we would have enough time to see things if we drove from Concord because it would be less expensive that way.
