Jim's mention of the eagle reminded me of something that happened last year. My brother, my wife, and I took a week long vacation in snowmobile country up in northern Wisconsin. This was in January. We were out on a great groomed trail, my brother in the lead, me next, and my wife last. The trail was lined by trees and it was almost like being in a tunnel becasue of the way the trees hung over the trail, it was beautiful. All of a sudden a bald eagle flew up from behind me and started pacing my brother. The eagle was flying ~3 feet above my bro's head and matched his speed. The eagle did this for 10 mins or so. It was amazing to watch and my bro didn't even know that he was there! All of a sudden the eagle accelerated, pulled up, and landed in one of the trees. My bro saw him at that point but had no idea that the eagle was right above him for so long.
