The fun in downtown Winthrop will start with the 34th Annual Sidewalk Art Festival, featuring arts and crafts by local students and artisans, including paintings, sculptures, photography, and quilts.

There will also be live music by The Bailey Ukulele Band, The Stone Quarry Band (with special guest guitarists), and singer-songwriters Peter Carriveau, Stan Davis and Ed DesJardins.

And for the first time, Porta Potties will be available.
