December brings houses and trees glimmering with holiday lights. In Petaluma, even the boats get dressed up for the occasion, their twinkling colors reflected in the waters of the Petaluma River. See the display of decorated vessels—from yachts to kayaks to one-person paddle boards—at the free Lighted Boat Parade at the Petaluma Turning Basin in Petaluma on December 11, 6:30–7:30 p.m. Find out more at visitpetaluma.com.
