In August 2015, I walked St. Cuthbert’s Way on the border of Scotland and England. As part of my documentation process I left 30 postcards, stamped and addressed to myself along the trail in the tradition of the 19th century walking practice known as “Letterboxing.” With each postcard was a note asking fellow walkers who encountered the postcards to send me a postcard telling me about their own experiences on St. Cuthbert’s Way.
