One Gloucester resident we met seems unlikely to get upset over traffic jams. Artist Jon Sarkin is too busy creating art in his downtown Gloucester studio, making collages, multimedia constructions, and colored penciled drawings. The subjects: Cadillacs, cacti, aliens, and other non-Fitz Hugh Lane themes. "My stuff is not the Motif Number I, seagull, fishy type of stuff," Sarkin acknowledges dryly.
