Read this interesting article in the nyt.com about bicycling through West Virginia, and was struck by the language used in the article, because it sounds like, well pilgrimage:
"Soon afterward we came face to face with the 3,294-foot-long Big Savage Tunnel. Inside, the tunnel was dreamlike, like a Roman catacomb or a secret passageway between the Great Pyramids. Every hundred feet or so a pale yellow light hanging from the ceiling showed the way."
I know on the Camino to Santiago de Compostela you can bike along the way, along with horse riding, though the walkers who walk (and don't ride on buses or put their luggage on buses going before us) sneer at these folks.
Can there be a pilgrimage by bike?
