Well, if you decide to roll rocks again, at least yell "rock" at the top of your lungs and then wait a few minutes. If someone is below they will yell back various obscenities. There are some pretty obscure rock climbs in the Sierra so do not assume you are the only one on the mountain.
The fellow who rolled the rock and killed the climber did not go to jail but he will spend the rest of his life knowing he killed someone.
Grab your bear can or camp chair, kick your feet up and chew the fat about anything Sierra Nevada related that doesn't quite fit in any of the other forums. Within reason, (and the HST rules and guidelines) this is also an anything goes forum. Tell stories, discuss wilderness issues, music, or whatever else the High Sierra stirs up in your mind.
