There were a bunch of new/planned superchargers added back in October throughout NY, and I think a new one in Ithaca was missed (it was on Tesla.com around the same time). It’s listed as in development just like most of the others in NY.

Based on the Tesla pin, it very much could be at the far end of the Wegmans parking lot - but I haven’t seen any work there yet, at least not as of a few weeks ago when I was up there last.
