It seems that elevation has an effect on a lot of us. It sure does make it hard to breath. And then, maybe from the lack of oxygen it seems to make us more sleepy. It seems that most days we see quite a bit of this.
Again, disregard the look I have going here. Not the best picture. I wasn't expecting this photo op! It was a hard morning for me. Cooking and reading sure does take it's toll on you!
