One of the most fulfilling things about working on a widely-used product is seeing what users do with it. A colleague of mine created this amazing account of his multi-night hiking adventure in the Sierra Nevada. He used a number of tools to document this trip, including Google Earth, topographic software, a digital camera, several GPS devices and a solar panel device. Us geeks really know how to get away from it all ;-)
The result of these toys and his diligent tracking is the incredible presentation on this web page. I like how he used Google Earth to visually depict the difficulty of certain legs of his trip. And of course, the photography of the adventure is very inspiring. I am already planning a similar trip in the High Sierra next summer.
