Marty Walsh will finish the day with supporters in Southie, watching the Bruins season opener. City Councillor At-Large John Connolly has a mid-day walk through Grove Hall businesses on his agenda.

ARROYO AND BARROS TALK ENDORSEMENTS AND ‘MONOLITHIC’ BOSTON: City Councillor At-Large Felix Arroyo and community activist John Barros both appeared on Boston Public Radio on Wednesday. The two former mayoral candidates said they had spoken as the race started up earlier this year in an attempt to figure out if it made sense for both of them to run. “We thought we had enough space for both of us to run,” Barros said.
