Rec league baseball games haven’t yet started here in Chelsea — they start next week — but that doesn’t mean the kids haven’t been busy: teams have been hard at work practicing for several weeks now.  On Friday I dropped by the baseball fields at Beach Middle School and photographed a few minutes of one team’s practice.  (The team happened to be sponsored by Arctic Breakaway, a fine restaurant that has consumed more than a few of my hours and my dollars.  You should try it out!)
