JON BODELL / Insider staffAs though you needed any more signs of summer being truly over, here’s another one: Everett Arena has transitioned from its summer schedule to its winter one, which means the ice is back. Gone till next summer are the antique shows, train shows and roller derby competitions, replaced by loads of hockey games and public skating. We went over there last week to see what was happening, and people were already lacing up the skates – the ice skates, that is – and getting after it. Above: Carter Locke (right), 5, gets an ice skating lesson from his dad, Nate, last week. There were a few slips and falls along the way, but that didn’t stop these boys from having an ice time (see what we did there?).
