The mature Burr Oaks on the farm are just like so many other older trees in Iowa - much of their leaves and cover are well above the heads of the humans when the stroll under the canopy. It just so happens our two-story farmhouse allows us to look out those 2nd story windows and observe some of the activity in the branches of these trees. But nothing compares to those rare moments we climb up to the attic and onto the flat roof.
