Ender's facebook page just highlighted that the Eroski site now has stage descriptions for the Salvador. This certainly means that traffic will continue to increase. I have walked the Salvador twice, and was with friends for the first two days on one occasion, but that was the sum total of the pilgrims I saw. I guess that won't happen again.
