Good for him. I say go for it while you can. This summer we had my oldest grandson (16) fly out to Fresno to join us on our trip. We went to Yosemite, Bryce, Zion, Grand Canyon, etc. One of my most memorable moments (maybe for him too) was when we took off early one morning, just me and him, to get the right lighting and to beat the traffic near Monument Valley. We took turns taking each other's picture in the roadway at the Forrest Gump movie scene. Sometimes the most simple things can be the most important.
