1 in 34,000 death bring on a do something, do anything response many here. What search and rescue did was temporary and meant to be just that. There were many such responses on Mt. Baldy, still people died and people got lost. My guess is the lost is down with the addition of the signage but the deaths will be back this coming winter when the willfully ignorant return with their Microspikes and trekking poles.
Your response is to do something outside the rules and regs, which by definition is a non-permanent response. Why don'cha call the rec. officer for the Inyo and do this the right way? I know all the forests love what their volunteers do for them.
