SUMBA, INDONESIA—When I bid on an “Eco Resort Experience” last March at the Christie’s Green Auction, I thought we were probably headed to a typically exotic deluxe vacation spot on the other side of the world. It turns out that I was in store for one of the most memorable experiences of my life, reminiscent of Marty McFLy traveling in his “Back To The Future” DeLorean car. A visit to Nihiwatu in Sumba, Indonesia is truly a trip back in time.
