There’s no agenda, just drop in for caffeine and conversation and to support a Groton business. Dutch treat. Groton local thanks Joan Reardon, proprietor of the Market for hosting. Next month’s “Coffee Out” is Saturday, April 30, at RiverBend & Co., Inc., 768 A Boston Road (Rte. 119-Shaw’s Plaza) with owners Donna Spanos and Dave Malek hosting.
