a Happening of Harleys

Don't know if a 'Happening' is the correct term for a large group of Harley Davidsons, but it was the best I could think of. We 'happened' upon them when driving home and just had to stop and take some blips. Probably about fifty bikes in all, from twenty two countries, doing trips to Stirling Castle, Edinburgh Castle and then most importantly - Bells Distillery in Pitlochry.
