16 slow miles but not easy because of the heat. I took 3 20 oz bottles and drained them all with a few miles still to go. Guess it is time to start taking the bladder with me. It gets a bit scary out there in the desert when the water runs low. I did run into my first rattle snake of the summer. It was nice enough to give me a welcome rattle when I was still about 10 yards away. It was up in strike pose and did not stop rattling until I was around it and gone. Did I mention, I hate snakes.
