Valance field is ( if we're talking about the same place ), a private museum of old aircraft thats about 1/2mile north of the threshold of Rw08. I don't think that it's available for anyone to land at, as the approaches bring you straight across the threshold of 08. The guy just uses the strip to get new aircraft into the museum.
Just as an aside, if you get the chance when you're in the area, go and have a look, there's some great old a/c down there
You can find it in Pooleys, it's listed in the farm strips guide
