Higher and higher

We were amazed to see what may have been a pair of bald eagles flying very low over our neighbors and friends' house across the street; of course they may have been scoping out the chickens, which were out in the yard. At the end of the walk, I heard a hummingbird going ballistic; spotted it hovering above a tree in the same friends' front yard. It was really scolding, so I looked down into the branches to see if something was setting it off; there was a raptor-looking bird perched there. When it flew out, it looked like a peregrine falcon; another potential chicken raider.
I felt fortunate to score an afternoon climbing workout with our son. We had a good session, although neither of us was feeling very energetic. I'd like to be at the level of his lack of energy...
