A ledger of 115 walks and 8,934 km, from Kiso-ji and the Tōkaidō to the length of Manhattan, each with a map, a GPS track and links to the essays, books or media that came of it. There’s a 3D view, and the ledger sorts the big walks from the minor ones. It’s a good way to pick your next route, or to lose an hour in someone else’s.
