Playing in a tree in front of our old house when I was around 7 or 8. My brother was too scared to climb to the top, but I saw a bird nest up there and wanted to see the eggs. Climbed all the way to the top and found a good sitting spot. Poked my head out of the leaves and could see all around, as well as into the bird nest. There was a nice breeze so the top branches were swaying.
