The Town Clerk’s Office will have a display of our veteran’s books for you to view and perhaps find a family member. There will be displays from historical societies and living history groups, demonstrations of quilting (along with demonstrations) in the chapel, colonial homemaking, military drills (near to the site of an actual Civil War recruiting camp), Revolutionary soldiers, children’s games from days gone by, a display from the Long Island Maritime Museum, a biplane from the Bayport Aerodrome, and fire apparatus from the Islip Town Firemen’s Museum, making this a great day out for the family.

Among the planned events will be two scheduled walking tours of the Grange buildings with the unique story of the founding of the Town of Islip.
