It’s time to update those lists: Santa’s coming to Boston Harbor this year. Twice! On Saturday, December 9th, the big man will be visiting both Pier 6 in Charlestown and ReelHouse in East Boston, bringing a healthy dose of holiday cheer to both sides of the Harbor. There will be hot cider and cocoa for sipping, bites from the kitchen for snacking, presents for the kiddos, and photos with Mr. Claus (BYOC: bring your own camera). Santa’s sleigh will stop by Pier 6 from 1:30 to 3:00pm, then hoof it on over to ReelHouse from 3:30 to 5:00. The event is free, but to RSVP you should either post a letter to the North Pole or click here.
