I love to lay on the ground, or in a lounge chair, under a big tree and look up into the branches. It's a whole nuther world up there. These photos are from the big pecan tree in my backyard. I watched the squirrels scamper along the branches, making small jumps into a nearby tree and then into another. They quickly made their way across our yard and the creek and then they were out of sight. From my perspective, these branches are truly a highway in the sky.
