March madness is in the air and we’ve got plenty of ways to help you kick off the mania this weekend. On our radar: a chilly event at PSC, a consignment sale with rock bottom prices, a Japanese holiday celebration, a story time designed for tots, an activity with our favorite blue fish and an evening for little dancers. If you’re looking for even more family fun, the Seattle Bike Show returns this weekend with the best of biking (think products and gear galore) and Mighty-O Donuts in Ballard is hosting a grand opening celebration for its new parklet with origami boat-making, boat races and of course, lots of delish donuts!

In honor of the Japanese Holiday Hinamatsuri, or Girls Day, enjoy dress up and story time, and make your own artwork inspired by the Japanese doll display on view!
