How can I communicate with my ski partner if we get separated?
My girlfriend and I like to ski the steep trees inbounds and out. Naturally, as we seek out and destroy helpless powder stashes, we often become separated. Two-way radios are ineffective because of their line-of-sight requirement and yodeling is often obtrusive. Is there a GPS system that monitors the position of multiple transceivers and communicates their relative positions to each other? Mark Aspen, Colorado
