In the pantheon of the manliest men in history, one common thread ties many of them together: facial hair. From the distinguished mustache of Theodore Roosevelt to the full beard of Davy Crockett, there’s no shortage in ways to wear the hair. This week the Petaluma Brothers of the Brush present the North Bay’s premier beard competition at the 56th annual Petaluma Whiskerino. Men, and women, from around the Bay come to show off their chops—whether it’s perfectly peached fuzz or business beards, classic goatees or freestyle sideburns. The fam-friendly event this year also boasts live music before the judging. The Whiskerino takes place on Saturday, Oct. 18, at the Phoenix Theater, 201 Washington St., Petaluma. 2pm. $10 to register. Free to watch. 707.762.3565.
