I count several different gang hand signal in that photo.
Just wanted to unlurk to wish a Happy New Year to all here! This is my third anniversary of following this thread. (This forum served as an “article link aggregate site” for me starting many years ago, though.) Yes, I signed on just to say thanks to you all, and especially ransomnote, for helping keep me truly informed, not to mention sane, and oftentimes entertained as well, during this wild ride. I hope there are thousands of others who lurk here for everyone who posts. I would love to have most of you as my real-life neighbors. Cheers!
