Whenever my mother spots a redbeard, she makes the approach, takes the shot, and sends it to me. I know how it can be awkward at times asking a dude for a picture of his face to put on the internet (it still feels weird not capitalizing "internet" even though AP Style finally let us lowercase that shit), so I very much appreciate her contributions.
Here's a sampling of the beards she's snapped. My favorite is probably the curmudgeonly bartender. It feels like he's putting on a fake grump.
