As Jackkdaw has explained, we don't usually host Thanksgiving events not only because it's not an international holiday, but it's also a bit close between the Halloween party and the Christmas party, which would make planning, organizing, and creating a map difficult and extremely time-consuming. For those reasons, we usually stick to parties and events that everyone can enjoy, and ones that we can properly devote our time to. You're more than welcome to start up your own party, though! I'll lock this up for you since your question has been answered. c:
