Hmm. You should have my twitter feed (lots of SAR groups and individual SAR members). And in fact, since I make a point of being friendly to them, sometimes they just give me information. But seriously, several SAR groups take photos and publish what they are doing. They even write up case studies. Maybe they all end up getting kicked off, if they do, many of the ones posting are quite young (20's).
(I'm in California; technical SAR people - I won't name groups - also give a lot of information out on SM once in a while).
