Out of an abundance of caution for Newtown residents, the upcoming community conversation on the future of the Fairfield Hills campus scheduled for this Monday, has been canceled.  Alternative arrangements are being planned and First Selectman Dan Rosenthal says they will be announced as soon as possible.  Town officials are discussing future uses and development on the former state psychiatric hospital property.  The Selectmen will hold the Board of Selectmen meeting that night for regular board business; Fairfield Hills will not be discussed.
