the 100 year club is a subreddit of people devoted to meeting up on january 1st, 2117, at the washington monument!
i probably won't live long enough to attend the meeting, but if i do, then i'm going to bring a perfectly preserved 21st century snowball!
hopefully the earth is still cool enough then for snowball fights to still be a thing.
if you're wondering what you can do to pass the time while waiting for the meeting, here is a list i've crafted of things to do in the meantime!
