It’s one of the signs that summer is almost here: Washington’s first farmer’s market of the season is this week. The market is open every Thursday May through October beginning at 5:00 PM on the square. It gets some accompaniment later this month when the chamber begins its Thursday Night Live events. The first one is May 27. It features the music of Say Uncle. Then in June the Washington Municipal Band joins the ensemble. Their first concert is slated for June 10.
