Yesterdays ride

Looking at my maps, I wondered why Id only managed
Arrochar to Tyndrum on last years ride. Yesterday I
found out as I cycled downhill for miles and miles
observing northbound.cycle tourists flagging on the
A82. The road only became busy at Tarbet where, last
year, I saw a bag piper standing close to a wall and
playing his pipes while facing the wall and taking
instructions from his teacher. I think that facing a
wall is one method of practicing the noble art of
piping. Dont know why though.
