Friday is the annual “Bike to Work Day” and it’s the first-ever “kidical mass” event, which also coincides with the Ballard Summer Streets event. Families with bike riders of all ages and experience levels will meet at Bergen Place Park at 5:30 p.m. and take off down Ballard Ave at 6 p.m. to the Burke-Gilman Trail at Fred Meyer. They’ll follow the trail through Fremont and Wallingford to Gasworks. You can sign up for Kidical Mass here.
