Yes, the bank would have been closed. It's an odd collaboration between them don't you think? Getting down there takes some effort, it's quite a walk from the window entrance on the bank yet someone has brought down the whiskey.
Another explorer who went a week later told me he met someone down there, who was not an explorer. You get all kinds of mental-cases sometimes. I'm glad it wasn't me.
Wow, that would be scary! Especially in such a confined space. I wish I could have seen the dynamic of the place when it was operational. Definitely an interesting combination!
