This years theme is Under the Big Top and encourage participants and artists to use that as their guide when chalking.  Chalk Fest is a family friendly event that brings hundreds of people to downtown Greenfield and where everyone can be an artist!   Squares will be available for purchase starting July 27th on the Greenfield Main Street website.   If you are a vendor interested in having a booth at the event please contact the Greenfield Main Street Executive Director, Debra Smith at debra@greenfieldmainstreet.org for more information.
