Chouinard financed his early climbing trips by making pitons and selling them from his car. Of course, my mind immediately goes to other potential markets. Who will do this sort of thing on the east coast for the Appalachian Trail? Who will do this driving from one ultra race to the next? Who will finance their first European trail running experience, going from one big mountain race to the next, with some version of this? Will a newly minted Physio dirtbag climber set up shop from their van at Camp Four this fall and next spring?
