I pooped along to the Antiques Roadshow at Wrest Park last Thursday. It was free entry...
It was very hot, and would say that there was a general lack of shade provided, but was a lovely atmosphere.
You had to queue to be registered, apparently it was around a 3 hour queue, and then you went on to queue for the experts for 1 to 2 hours....
We didn't bother to do any of that, had a nosy around and sat and had a coffee!
