May-June Sojourn began with a rush to the airport, a gin and tonic in the Exec lounge, and a full flight, mitigated by a very nice traveling companion named Mark that knew all about my first desinaton, Edinburgh. Princess Street , Grass market, Plasir du Chocolate, Eninburgh Castle, single malt scotch-- every thing one must pack into two days in the ancient city.
Aided and abettted - slept for a few hours and arrived in this ancient city.

So there are pipers everywhere-- mainly for the tourists but not exclusively-- why did I draw that concluson?

Because they are not only on Princess street-- they are in the BBCs workshop in the square outside the Sheraton - along with soap opera stars and talk show hosts.
