When I went up and down the Royal Mile, I don't remember any busking pipers. There was a piper at Blair Castle, which was just after my visit to the Killiekrankie Visitors Centre and then Battlefield (private property). The piper was a 10-year-old boy who was quite nervous when I told him I was a piper, too. He was not a master piper, but I was quite ready and happy to listen to him.
