Perhaps you are one of those people who loves carols so much you sing them year round: “Joy to the World” when summer break is over; “Hark! The Herald Angels Sing” at the morning alarm; “Frosty the Snowman” when enjoying an icy treat. If you are one of these people, December brings special fun: Carols are not only in season, but there are other people who are eager to sing them with you—in public! Find them at the free Community Carol Sing at Walnut Park in Petaluma on December 23 at 7:30 p.m. See petalumafirst.com to learn more.
