She wrote a detailed response on a local, Hollis Facebook group. My wife is a part of the group (we're on Rocky Pond Road, but not connected to the pond at all) and I've asked her to share the link with me to post here; I'll update the post when she does, although not 100% sure that non-group members would be able to see it.

The response was well written, detailed, and seemed credible to me, for what that's worth. Essentially she alleged that the issue stemmed from someone affiliated with the pond trying to sell the land to the town so they could keep it open, as they were done handling it after 20-30 years, and they included acreage that belonged to a HOA in their proposal ("open spaces"), which was only discovered later and tanked the deal for some reason. She also alleges that the writer is a former political opponent and that this amounts to an "October Surprise" that is politically motivated.

She does a better job defending herself than I did, but that's what I remember of the letter.
