Well, I was there yesterday. The grass areas on site were pools of water.
Heading out at around 1630, the car park areas and some camp sites were akin to small lakes. Some of the parking looked OK, but the entrace was under standing water.
The rain was in very heavy bursts, on and off all day. Hats off the people in the air Friday, well done given the conditions. We did wonder how they would cope on Saturday, when we got home and heard the news it did seem like the best decision.
I do know the Queen managed to escape all the rain, she departed the parade ground for lunch and the heavens opened - people were soaked through in a couple of minutes. The RAF people still marched off as if nothing was going on.
Still saw some pretty good practice flights though, and the fly past was great.
