@neilnjae but those different choices don't need the same info, nor the complete state of blizzards over the full area.
stateIsSafe :: OriginalBlizzards -> Time -> Place -> Bool
stateIsSafe b t p = -- look t steps left of p for a blizzard going right (and vice versa for the other directions)
Since you don't want to re-visit states anyway, it should be computed only once.
#Twitter suspends #Mastodon account, prevents sharing links: Our statement
https://blog.joinmastodon.org/2022/12/twitter-suspends-mastodon-account-prevents-sharing-links/
On Dec 16, Twitter suspended our @joinmastodon account after we shared a link to the newly registered Mastodon account of @ElonJet, an account that broadcasts public flight path data of Elon Musk’s private jet, which was previously suspended from Twitter itself. At the same time, accounts of multiple journalists from major publications such as CNN, The New York Times, The Washington Post, as well as various independent journalists, were likewise suspended for either linking to the account itself or talking about the event.
