Oh yeah, when you go more than ~5 miles or ~24 hours of self-powered evacuation to a TH (~your comfort zone for reaching advanced medical assistance) - purchase a PLB and take it with you. Spend a half hour at a troop meeting introducing Scouts to what it is and when you activate, and show them where you keep it in your pack. You will have just made you scouts that much braver and more capable in an emergency.
