Honk!, a yearly festival of activist street bands, starts Thursday. Sunday is the parade from Davis Square, Somerville to Harvard Square, Cambridge. It starts at noon and ends around 2pm.
Extinction Rebellion (XR) Boston is marching. If you want to raise the Jolly Roger and help with their effort, meet at Herbert and Day Streets in Davis Square around 11:30am. Bands and community groups will gather at the parking lots on either side of Day Street.
It is a quick walk from the Davis Square MBTA Red Line station and various bus routes. See our conference page for transportation details.
