Join LexCAN at Lexington’s Discovery Day Street Fair at Lexington Center to learn more about what we’re doing. Hosted by the Lexington Retailers Association, Lexington’s Discovery Day is designed so that the public can “discover” what Lexington has to offer. Held on Mass Ave in the center of town, Discovery Day seeks to highlight Lexington’s many businesses, cultural and civic organizations, and municipal departments while featuring food, entertainment, and more.
