This is a good thread. Sorry for jumping it as a newbie, but I wanted to add something:
We leave our itinerary with a couple people and an easy to find copy in the car. We always include worst-case scenarios for bailouts, route deviations, cross-country, or foreseeable delays. We also use the absolute drop-dead date for calls to be made, and that number to call if it comes to that. I don't care if my GF or anyone else can decipher a word of it, I write it for SAR to understand, and I leave specific instructions to do nothing more than recite it, verbatum.
Discussion related to Sierra Nevada current and forecast conditions, as well as general precautions and safety information. Trail conditions, fire/smoke reports, mosquito reports, weather and snow conditions, stream crossing information, and more.
