Most people think of Mardi Gras as a time of serious partying. And thanks to local fundraisers, its indulgences can also benefit good causes. For instance, proceeds from the St. Mary of the Angels Catholic Church Mardi Gras Celebration will go toward repairing the school’s roof. The revelry will include cocktails, dinner, gaming, and dancing with DJ Larry Thompson, as well as live and silent auctions. The good times happen on February 22, 5:30 p.m.–midnight, at the Redwood Empire Fairgrounds in Ukiah. Tickets are $60. Lest children feel left out of the adult-only evening, there is a kids’ carnival planned for February 23, 11 a.m.–3 p.m., also at the fairgrounds. General admission is free; tickets for rides may be purchased. Meanwhile, the Children’s Museum of Art and Science Mardi Gras fundraiser will include a kids’ music parade, games, costume and mask contests, dinner, and live music. The event will be held on February 22, 4–8 p.m., at the American Legion Hall in Clearlake. See facebook.com/cmaslakecounty to purchase tickets, which are $25; ages 11 and younger get in free with one paid adult ticket.
