I was “up north,” walking through the woods with an escort of dragonflies on either side, as if I were a visiting dignitary in need of protection.I love dragonflies. I love their variety and their shiny wings and the way they turn on a dime in midair. I love how they clear the path of mosquitos as I walk through the woods along the lakeshore.

Then it started again. “Someone must be playing the pan flute!” I amended, listening to the music rise in volume.Then I heard it coming from the other direction.“What the heck?”I turned around and stared at the shore. It was obviously a flute, but now it was coming from both sides of the dock. It made no sense at all. For a moment, I wondered if I was hallucinating. There was music coming from the woods in ...
