| Notes | While we were near the end of the Wildlife Loop at Rocky Mountain Arsenal NWR I noticed in my rearview mirror that our trunk was open. Check the scope, I said. It wasn't there – we had left it behind at the last stop. We reversed a few hundred yards very carefully, and fortunately found it on the side of the road! We met our daughter and grandchildren at Lake Mary for a few minutes – they were there for a walk. Our 7 year old grandson Oliver who loves hawks found and identified a distant Kestrel on a wire and 2 BE in the sky that I needed binoculars to see. His 4-year-old sister not to be outdone found us what turned out to be an adult Golden Eagle! I told them that if our route had not lasted all day we would take them with us, for their sharp eyes. | |
