To be fair, I think people remember things differently than they actually happened. It’s natural to remember all the big snowstorms and forget all the other winters that were complete crap (which, let’s be honest, most winters in the SC midlands have been for hundreds of years, it’s just a marginal snow climate). I don’t doubt that it used to snow somewhat more in CAE, FAY, etc., but these were never places with regular significant wintertime snowfalls, at least not in the last couple hundred years. It’s not like FAY or CAE had even the snow climo of 2021 CLT a hundred years ago.
It’s similar to how people talk about how it just doesn’t snow as much as it used to when in fact the 2010s were almost certainly much snowier across the Carolinas compared to the awful 1990s, which everyone seems to forget for some reason.
