Skateboarders may resist their culture going mainstream but it seems inevitable when the venerable Smithsonian Institution creates Innoskate, a festival started in 2013. The Polk Museum of Art, 800 E Palmetto St., Lakeland, jumps on board with "All Decked Out," an exhibition of painted decks, such as those by Dan Lasata, shown here, photography, drawings and sculptures curated for the museum by Chad and Suzie Cardoza. It opens Saturday with a free reception from 2 to 5 p.m. with some artists on hand. It continues through July 20. Admission is $5 for adults, $4 for seniors and free for kids and students with ID. Free on Thursday. (863) 688-7743; polkmuseumofart.org.
