This is somewhere near the middle of Sarria and Portomarin, Brierley's stage 29. More specifically between the alberque Molino de Marzán at about 107 km to go and km 102 to go where we found the Galician bagpiper busker. Its the best I can do for you.
@Rick of Rick and Peg - Thanks, if I recall correctly I rode about 10-15 km that morning (starting from Barbadelo) in fog and/or missed it was difficult enough to ride and not take out any walking pilgrims. In fact at one stage the fog was so thick I got lost and had to back track about 2 or 3 km to pick-up the turn off. Cheers
