We don't yet have the established pilgrimage circuits that exist in Asia, obviously. But the practice is afoot anyway. (ha! afoot!) Not counting the version we practice at TBI, there are at least two established paths: one in the Adirondacks of New York, and the other at California Tendai Monastery. http://www.caltendai.orghttp://adirondacktendai.org
Doko, if you're reading this: do you guys practice kokorodo at all? I'd think Colorado would be a natural one for this.
