Official crowd estimates for events like the annual Seattle MLK Day march are hard to come by but organizers said Monday the 2017 gathering might have been the largest in the 35-year history of the event.
You could also measure the crowd by the CHS video — four and a half minutes to walk from the start of the procession to the SPD contingent bringing up the rear. The marchers passed from Garfield High School to E Union then E Madison and onto the Federal Building downtown.
