The Newtown Planning and Zoning Commission is holding a public hearing tomorrow night on a proposal to allow food trucks at farmers' markets.  A one year trial period was approved in 2016, allowing a small number of food trucks.  When that year ended, the Newtown Farmers Market did not come back to the Planning and Zoning Commission to make the feature permanent.  The market has been held at various locations over the years, but this year is located where Woodbury Hall stood, before being demolished.  The Commission's meeting tomorrow is at 7:30pm at Newtown Municipal Center.
