Halhiker,
I feel compelled to respond to your post under "Two ways to reduce..." and I started this as a separate topic with the hope that others read this message.
It sounds as if your bragging about your freedom from tech in the wilderness ("No GPS, no cellphone..."). But please stop and think about how you would have felt if you had been with your friend Ellen when she broke her leg and you had no means of communication.
... or if on one of your many hikes you came across a person in distress who needed urgent care. How much does a cell phone weigh??? Almost nothing. You might carry it 99 times and not need it, but on that one occasion it could be worth its weight in gold, and it might just save a life.
Granted, cell phones don't work everywhere on the mountain, batteries die, and they aren't foolproof, but many rescues have been initiated because lost people were able to call 911. And they've helped make the rescue operations faster and safer.
I encourage everyone to carry their cell phones. Many are now equipped with GPS. Even if you can't get service, at night the helicopter crew can spot the light from your cellphone from miles away with their night vision goggles. Just remember to turn them off before you start your hike to conserve battery power.
Accidents happen. Even to the most experienced hikers (like Ellen). Be prepared for the worst; always carry the 10 Essentials and that now includes a cell phone (a sat phone would be even better, esp. for solo hikers).
