It seems I was a little bit mean to The Royal in my last post. We have three taps and they all have water in them, apparently the taps were there yesterday but not the water.
A chat with the man in charge of the penning has revealed the 'truth' behind the extra pens. The NSA building, being of timber construction, has posts every 15 feet. If a pen has a post in it it doesn't count as a pen. The spare pens which don't have a post are apparently in case people turn up who are not on the plan - last year they were many. Why spare pens in ones or twos would help with this I'm not sure, but it looks better than having a block of empty pens in each breed section.
On the bright side, maybe someone from the Royal read my comment about no lights. This morning some electricians appeared and put up a few temporary floodlights.
