THE PERFECT ENDING after playing a game of softball on a hot day Tuesday was stopping by the North Reading 7-Eleven to get their free, ice cold Slurpee on “7-11 Day.” The kids and their siblings who enjoyed this free annual tradition were (front row, from left): Maddie Moran, Trip Callahan, Cora Rosabianca, Finley Allison and Trip Moran; (back row, from left): Willow Allison, Charlotte Callahan, Emme Sawyer, Gabriella Norwood, Francesca Giordano and Mia Rosabianca. Slurpees were introduced by 7-Eleven in 1966 and more than 7.4 billion of the drinks have been served in the decades since then. (Marissa Rumasuglia Photo)
