We’re riding home with groceries when a small white shape scampered across a yard and jumped onto a stump:

If you’ve ever seen a gray squirrel, you’ll recognize the shape, even in this gritty enlargement:

Wikipedia says this one is likely a leucistic white squirrel, rather than a true albino squirrel. There is, of course, a website. tracking “white squirrel” sightings.
The relevant coordinates, for science:
41°41'39.9"N 73°52'56.6"W
41.694410, -73.882374
Can’t say if this one had black or pink eyes, but it was pure white!
