What is that ladder shown at the end?
Gosh I didn't see that the first time around. I stopped before the end. Uh...that's clearly big enough for a man to go down.
I really wish we had the answer to this. The photo you posted showed a super small hole. I can't imagine anyone even thinking they could fit a child's body through there.
My feeling is it had to have been bigger than that.
We are getting so many different answers.
