I go through Gilmantown Road every time I drive up there. It's a soft of "long cut" around the Wells area. I'd almost bought land there a few years ago that just touched a small lake. Gilmantown Lake (I think).
Some years ago I met a farmer who runs a farm on the very end of Otsego Lake. I bought a Case tractor from him. A DC with a dropped valve as I recall. Maybe the farm was in Sringfield Center or Richfield? I think he told me it was one of the last farms there. I think I recall the name Tim Richards on Public Landing Road - but my memory could be off. Fasset Farm maybe?
