On a very early spring evening after my very first tour guide meeting 10 or 11 years ago, I took a walk down Poplar Drive. Thinking I heard a squirrel scrabbling around, I went to explore. There instead of a squirrel was a flow of sap from high in one of the poplars splashing down the side of the tree as if from a garden hose. I left after watching it for about 10 minutes. Amazing!
