This morning, on a single circuit of Kensington Gardens and Hyde Park, I personally counted 144 snow persons. (*)
My, our neighbourhood's pretty in the snow (and at other times).
My methodology might reasonably be questioned. At first I was counting virtually anything snowmanlike. But not too far in, by about Hyde Park Corner (the SE corner I start at Kensington Palace, the SW corner), I concluded I'd been being too generous. A lot of these things were, frankly, just big single balls of snow on the ground. Maybe they used to be snowmen; maybe they were yet destined for snowmanhood. Or maybe, more likely I think, they'd been abandoned mid-project.
So from then on out I was looking for either multiple, pyramidal levels of snow physiology; or else facial features, appendages, headware all the sorts of things that imply snowpersonhood. In the end, I expect I overcounted a few random large balls of snow; but I'm more sure I undercounted a bunch of indistinct snow figures in the distance, in the interior of the park.
Either way, a gross of snow persons is a big snow population. We can call that a supported snow company.
