Otsego County 1980 Highway Map
Historical Marker
- A letter was written 7/3/1964 by G. Dorothy Williams with comments about cobblestone structures in and around the northern-most Towns of Plainfield and Exiter, Otsego County area. Editor's Note: Unfortunately the locations of these structures are not provided. Some of these structures are likely in nearby Madison, Oneida and/or Herkimer Counties which border these Towns. If she did provide additional information to the Cobblestone Museum as noted in her letter, the information would have been included with the appropriate structure pages in the Cobblestone Info Base.
