Ski Tracks on the iPhone

It turns out there's a much less expensive way to capture most of the data that matters. Before Greene left for Whistler, he spent 99 cents on iTunes to download Ski Tracks, an app created by Core Coders. It uses the GPS technology in an iPhone to capture data including speed, distance, vertical descent, number of runs, and more. It can't check the data mid-run, but Greene didn't really care much about that feature anyway.
