I think this quote from a news report sums it up:
"Thursday, the Inyo Search and Rescue sent in a helicopter and pulled the three men out of the snow and cold. ...
Inyo Sheriff Bill Lutze confirmed that Inyo and the Sequoia Kings rescue team went to work on this case. The three missing men had been part of a group of 8. When the weather turned bad with white-outs and three feet of snow at the start of the week, five of them decided to leave the Sierra. The other three vowed to go on to the top."
I make a vow every trip. I vow to get EVERYONE on my team back to the trail head safely. If you hike with me as a leader, you stay with the group. One quits, we all quit. Everyone gets back to the trail head. Everything else is a bonus. That's just me, your mileage my vary, to each his own, etc, etc...................................................DUG
