This may be a bit outside of what you are looking for, but when I hiked the Pacific Crest Trail, there were a couple of widely beloved “Trail Angels” trail-named Ziggy and the Bear who had a place near the base of Mt San Jacinto. They were situated after one of the longest descents of the whole PCT (11,000-1400ft over a dozen or so blisteringly hot miles). They provided shade, salads (a real treat for the dehydrated food eating hiker), foot baths, rides to town and REI, all around great hospitality and trail stories. They were probably 80 when I met them in 2012, so I doubt they are still as active (but I sure hope they are!). Basically, they were great folks to meet in your area, and being a trail angel like they were in that brutal but beautiful stretch of hiking would connect you to some wonderful hiking folk, who in my
experience are often primed to become permies once they finish their long walk to Canada/Mexico. If nothing else, they have great stories, the ability to work hard and steadily for 8-12hrs a day in any weather, and can sleep outside happily.
I also took my initial Wilderness First Responder course at Big Morongo, and these and Wilderness First Aid classes are great ways to develop life and money saving self sufficiency skills while meeting other altruistic, outdoorsy folks. It is also remarkable how much fixing leaks in plumbing and human circulation have in common.
