Every first Sunday since 2016, the loose coalition of do-gooders under the name "PMA Bike Ride" has been gathering to buy pizza at local shops and hand it out to people on the street. This weekend is no different — and you don't need a bike to participate. West Philly folks should meet at Rosa's at 1 p.m.; the South Philly spin starts at 4 p.m. at Cacia's.
