And not so long after the loss of THV, and the remaining buses being spread out across the region...

NEBPT reported a while ago that they also had accommodation challenges, as Wardley needed a new roof. I think that's what led to the sale of a few of their buses?

Ideally what is needed is some joint working, actually work towards some kind of museum and heritage centre, but in the absence of that, I'd suggest that the best bet is to map out all the farms within a radius and start making contact.
