Thanks Dai, but I'm still a bit at sea. (I get confused crossing the Herts Essex border in either direction - anywhere outside the Harlow Republic.)

Clearly York House is significant, but I'm still not clear about its role.

I mean, is it a private dwelling, a community centre, a pub where people are singing, a place where there are floors to lie on, or a meeting point where arrivals will be redirected to somewhere else?

And is there anyone who need to be informed of impending arrival? Any money to change hands? Any time before which not to arrive or after which not to arrive.

No doubt all this is in some previous post that I've been unable to find, or scattered around in a selection of posts. But I don't think I'm the only person who would appreciate a summary.
