Maybe Californians have never seen a bare tree, so have no idea. In my opinion, if they don't have bare or leafless trees/bushes, etc. in their bast storeroom of props, or a bare tree/snow covered backdrop to use, then, during the winter, they should not use that "park" setting at all. They would be better off with the docks, the storefronts, doorways, etc.
It is winter, it is cold, (and currently, another snowstorm has swept across the midwest to the east/northeast. Airports have been closed, schools, but that vacuum where Salem exists is just untouched. Lakes are frozen, snow everywhere, but no one even wears earmuffs, let alone the boots and gloves/mittens. Kids are so bundled up in the midwest...but, Salem is the magic kingdom or something. LOL
