Water City Sports Center and Hockey Center has long been the definitive county home of roller hockey and roller derby. But its brand-new, lesser-known identity as a public skating venue might be more relevant to locals and visitors alike. Sundays 1-4pm it opens with DJs catering to the crowd, a special “wading pool” section for kids and Skating 101 tutorials. 2800 Second Ave., Marina, 384-0144, http://www.watercityrollerhockey.com
