Only a few came up when I refined my search. Tried various phrasings, dates, and board categories. Then I broadened to "just underground tunnels" and all boards. Here is the link to the search results for that, most recent first. Still scrolling thru.

Funny. I remember discussion centered around NYC, too, And the speculation about the hospital ships and what they were allegedly being used for. And the "hospital" tents in Central Park. There was one pic, tho, of an alleged child in a hospital bed seemed to have animal or reptilian parts and if memory serves, had an oxygen mask? There were several medical people in the photo, too. I remember anons zeroing in on various aspects of the photo. Funny, tho, too, I really felt I had read about/seen that particular pic on half chan during the beginning months of COVID scam. The reason I think that is because I was either have a hard time getting to or replying on QR. Hard to remember it all. But I do tend to remember what I read and can usually find it again if I haven't saved it. Funny tho there is a suspicious lack of threads that come up during the time period in question. This one, tho, discusses it retrospectively:

Fuq me,
Thank you, but can't see the pics in that thread for some reason.
Always important. Sometimes fun. But hey, FWIW that's not the pic I recall.
That's a close up of a fuller one that I recall, yep.
NOTABLE
This place has really gone downhill as compared to the old days. Not even gonna lie.
