Hack into the NSA and setup a constant stream of smart phone location updates. Then using GIS mapping create a map of all the ski areas (every run) in the US. Then change the smart phone location updates so that they only track smart phones at said ski areas. Make a new map that records snow fall and layer it over the map that tracks skiers locations. Set up an alert so that every time there is more than say... 12 in of snow fall that you get an alert containing the amount of snow fall and the location of said snow fall on your smart phone. When you get the alert look at the map and look for skiers (using constant smartphone location updates) who are not on the trails. Make little notes of how many runs and what time are these runs.
Ski powder for the rest of your life.
Is it worth taking the privacy of every skier in the US so that you have pow locations forever? Is is even a question? Yes a million times over?
