There are many ways to allow your family and friends to track your smartphone while skiing. That's what I do, but it does require having cell service, unlike the law enforcement tracking technology.
The Adirondacks have terrible cell coverage once north or Glens Falls and south of Plattsburgh. The cell coverage at Big Sky is spotty unless you are in a "line of sight" location where the tower on Andesite is visible. This event is a good reminder to carry my avalanche beacon even when "in bounds."
