Scratch that, user error; it's still called "Mianus River State Park Scenic Reserve" in the latest dataset.

Aha. Okay, so, in the original dataset that I had, both of the areas in this AOI in the source dataset were called "Mianus River State Park Scenic Reserve". But in the latest one -- https://portal.ct.gov/DEEP/GIS-and-Maps/Data/GIS-DATA#Property -- the northern polygon has no name.

I'm sorry, I don't remember; the history shows me editing both parks within this AOI. (I think I was pulling in some geometries from a state of CT dataset...?) If I can find the original dataset, I'll see if they were tagged with a name.
