We went last year on the Saturday. (

It was a very enjoyable day out and the road run around the village was very photogenic.
However, as others had told me, space in the the Goods Yard is at a premium and in the middle of the day getting a good view of the exhibits was not easy. I find it hard to imagine how "wood sawing, threshing and road rolling" could be added to the mix, maybe part of the car park on the other side of the railway will be used?
