Walking along the improved stretch of Mass Ave in Arlington, I saw a couple coming out of the 13FOREST Gallery. They pointed at Mia Cross's painting Agnes and Avi in the front window. They seemed enamored of the sensitive, experimental portrait and talked excitedly about it and other work they'd just seen in the gallery. Inside, I overheard Marc Gurton talking with a guest about the layaway plan they offer. TENFOLD, 13FOREST's ten-year anniversary exhibition, which opened the night before is on view. Gurton said it represents the past, present and future of 13FOREST and its mission: to make art accessible to all.
