Is there a Regionals calendar somewhere? I want to find some in my neighboring states, beside ours in California.

Bogglingly, no. I've only seen information about 3 regionals, and they were all announced by the hosts and the only reason I know about them is I listen to Initiative One, who both announced their store's regional and set up a shared doc to compile other announcements.

I feel like with the state of local play the way it is, FFG is being really misguided if they expect people to find their way to the hosts themselves. Heck, many probably don't even know where to go for local play in their own town, let alone what stores run events hours away.
