Were you at the Open House? When I was there he was ignoring pretty much everyone and was half asleep. One of the grooms mentioned that the horses were expecting to be fed and then be turned out, and they (horses and people) were an hour behind schedule because of the time change.
Yes, I was at the Open House. He was ignoring everyone when I first got there, but then he came to the front of his stall. He seemed particularly interested in the two little boys who were standing right in front of his stall (one of them was my son). Mineshaft, as far as I could tell, was totally ignoring everyone. The Factor pretty much slept through the whole thing. And we got to see Union Rags try to take a chunk out of one of the worker's arms.
