The finger lakes are a lot of small towns, with Ithaca being "ivy league" but perhaps not enough wealth to support a lot of sales/service. eastern-Rochester - maybe since it is equidistance among the Buf/Roch/Syr/Ithaca region.
Local knowledge here: the service center should be in Syracuse, specifically in the northeast quadrant of the Syracuse beltway (which is missing its southwest quadrant).
Look at the highway map. People are used to driving to Syracuse from as far north as Watertown and as far south as Binghamton (as well as from as far west as Buffalo). Basically you can cover the whole state from there.
