Costumed kids, from mermaids to dinosaurs to ferocious lions, packed the Linden Square courtyard in Wellesley on Saturday morning, for pumpkin decorating and a little trick-or-treat warm-up.

While I happened to be there at the start, dressed as “sweaty runner,” I was only able to see the kids securing their pumpkins before adorning them with stickers and other decorations. I trust that they made the most of the situation.
