The story and all the photos are on Endurance.Net at http://www.endurance.net/international/Chile/2010EasterIsland/index.html
This photo is of the wrangler (native Rapa Nui riding in flip-flops ) that helped us select our horses for the race.
Horses are everywhere on Easter Island - very few cars, so people ride horses, and they basically have open range on the Island. Everybody knows whose horses belong to whom and they just graze them wherever it is possible. (for example beside this moai)
It was fun going back and reading the travel notes. While I was down there I had just seen the film documentary "180 Degrees South" - a road/boat trip down the pacific coast to Patagonia. The sound track by Ugly Casanova always reminds me of this time.
