Wondering what’s up with the Perilous Plunge this year? As with most things, it’s happening online, providing the same wacky (if not as wet) good fun as always while raising much needed funds for Redwood Discovery Museum and its uber valuable hands-on education for kids. See what the crazy and creative plungers have concocted this year as they post photos and videos of their dips, plunges, swims and more — to say nothing of their costumes — during the Perilous (Post a) Plunge on Saturday, Feb. 27. Visit www.discovery-museum.org/perilous-plunge.html or www.facebook.com/redwooddiscoverymuseum for all the fun.
