From the event listing:

It’s time to stop backpedalling Seattle’s biking, walking, and transit plans. Transportation causes too many deaths, climate change, and economic inequality.

Join us on Sunday, June 16 for a fun, music-filled, parade-like protest to call for leadership to boldly act on transportation. We’ll meet at Seattle City Hall, 1 p.m., for a rally then ride with hundreds of people down 4th Avenue to Westlake Park.

There will be live bands, public officials, and plenty of fun as we push Seattle leaders to take action.
