For us here, snow is so usual thing, but this year, there is no snow, i don't why, just rain and rain almost every day. And it's too warm for december. Only positive thing about that is that i don't have to scratch the snow and ice from my car every day, before driving to work or anywhere.
Christmas with no snow is pretty sad, but i guess it's the global warming, they talk about.
If you read between the lines it looks possible that the snow mode will be switched in on GTA5 for original generation consoles, not just the newer ones and PC:
