In accordance with Open Meeting Laws the notices of public meetings are posted on the bulletin board in Town Hall. In addition, a binder containing the postings is available 24 hours a day / 7 days a week. The binder is located outside the back door of the main Town Hall on the drop box to the left of the door.
Also, check the Town Calendar on the Town website. As a courtesy, the staff does try to post meeting notices here as well.
