That's super cool! Can the IA building be accessed by some random people like myself? Next time I'm in SF (who knows when that will be though) I'd very much like visiting it!

That's great. Ask and ye shall receive.

What's most surprising is churches notoriously have really sketchy electrical. There had to be some renovation in that regard, right?

Thanks! The church attendees (employees?) have a Severence Kier vibe... although I'm guessing the TV show came much later.
