That's how i understand it. I don't know how many of your are famliar with John Knight Park, i went for a walk there last weekend. It's got a big grassy area, which is where the ford people are going to be, since they need drip trays. The Morris club (Marques in the Park) people might either be there as well, or in the carpark at the top of the park. there was parks for about 100 - 150 cars in the carpark at a guess.
We'll probably find out more on the morning, it doesn't start until 10am, and we're planning to get there at 8am when setup begins.
but yes, there are 2 show 'n' shines in the same park
