I think that there are so many different ideas about what constitutes the Finger Lakes region that I need to clarify my usage of the term. New York is broken up into so many random areas that many of the places I've lived or worked have been considered different regions.
Depending on where you are in the Finger Lakes, other areas may or may not be included in the region despite being located on a Finger Lake.
