While news of a possible reunification of downtown Santa Rosa’s Courthouse Square heats up, a longtime tradition brings the masses to the Square this weekend for a chilly, though no-less cheerful, Winter Lights event. Santa Claus will be in attendance, as will a welcome wagon of entertainment and the best local food trucks, hot chocolate for the kids, and beer and wine for the adults. Kids can also enjoy activities like ornament painting and an ugly sweater contest. A candle lighting to remember and honor those no longer with us will precede the grand Christmas tree lighting at dusk. Winter Lights celebrates the season on Friday, Nov. 27, at Old Courthouse Square, downtown Santa Rosa. 5pm. Free. 707.545.1414.
