What a Happy pair. Some years ago my sons 5 year old Rottweiler "adopted" my 7 week old puppy. She was "Mom" to him until he died at age three. She never was the same after that. She missed him so much.
My concern camping on the desert would be of getting lost. When I boondock in a National Forest I have roads and compass...and just bought a TomTom. No roads on a desert, probably not cell service, do you have to stick close to a main road? Thanks, A...
