I went in a short while ago for their annual bash -
Boxted 2008 Fly-in
They used to have quite a decent airshow there, but, as I understand it, the farmer who has recently taken it over, only allows the one annual event there.
They are re-building a nissen hut there to house an exhibit of it's 8th air-force wartime history.
I suspect that it hasn't been mowed since the fly-in.
