I was a bit surprised to watch the pipers tune up their drones with the help of an electronic tuner. High-tech and ancient tech all at the same time. Very cool.
Treats were, of course, for sale - we bought some Welsh cookies from the InFamous Welsh Cookie man. MMmmmm. Also bought Scottish shortbread from the Ancient Order of Hibernians. I make my own Scottish shortbread, so it was interesting to taste a different recipe. Need to track down a recipe for the Welsh cookies - they were new to me.
