Any pinhole will do. My most memorable partial (haven't been in a total path yet) was at a house where the trees cast shadows against the neighbor's house, and there were hundreds of soft crescents all over the place from the leaves. Like a drive-in movie screen for the event.
I remember something similar with the previous eclipse, which I watched from a different park in Kentucky. But there weren’t any leaves on the trees here yet for that to happen this time.
Without the leaves, the shadows of trunks and limbs had hard edges during the eclipse where I was at with 80+ coverage. Like solid black ink shadows instead of the fuzzy shadows they usually have late in the day.
I guarantee there’s no way the building lasted 125+ years with holes in its roof, or that any but the poorest folks tolerated leaky buildings even back then. It’s overdue for maintenance.
