sleep eludes me

It is 12:30 and I cannot sleep. In the morning I am supposed to be up at 4:30 so that I can take pictures of Sedona at sunrise and the town of Jerome with my niece. I see a nap in my future tomorrow no doubt! So far, Sedona is beautiful. Bell Rock with it's red face is breathtaking. For the first time, I can see why some find the desert beautiful. I've always preferred the lush green of an alpine mountain landscape, but this has a unique grandeur.
