Also, I have had questions about the sketch plan that I previously posted. The loading doors at the side do not go through the middle of the stalls, I just wanted to indicate that there were several along each side of the building. On the days we have viewed the Cheese and Grain there have been stalls already set up which has made it hard to do a detailed drawing of the room.
Don't forget my earlier advice about lighting, especially at the sides. There are sockets, but do bring lots of extension cables in case you are not next to a socket.
