GPS especially for skiers

With winter here. many of us our planning ski trips. And those ski slopes can be quite confusing, so here's a GPS especially for skiers. If you are ever stranded anywhere or just plain lazy and need a ride back, this baby will send out an emergency signal. Besides this essential feature, there's something fun too. You can share your ski performance with total strangers or friends. The concept is to bring together location-based services with social networking. The Ski GPS sounds pretty nifty and I'm game for it.
