And not just cyclists! (Unless it simply means people who can ride a bike.) Do you care about air quality? Like to dance? Want to build community? This FRIDAY 6/26. Group rides like “critical mass” are so chill and yet powerful in my experience. Definitely recommend going a couple times if you haven’t b4. Volunteer marshalls make sure motorists steer clear of the group. There’s often music and fun bikes. Dance party at the end of this one :) #BostonWeekend #Boston #CambridgeMA
