Yes, I know you can see deer in almost any urban back yard. BUT I watched this cautious mule deer (I think) come down a large mountain side alone and easing toward the pool where a refreshing drink of water awaited. Yet an abundance of caution, as the recent phrase went, kept him alert. I was well protected from his sight by a bird blind but I knew he was aware of me yet he came so close and then from about 20 feet - five from the water, just stared. There were lots of birds to and fro but at the last moment he turned and went back up the mountain. I hope he returned and got the needed drink. Special moment at Davis Mountain State Park in Texas.
