Exscribbler is spot on with Leeming.
Next to the A1, accessible for both Southerners (providing the Customs people at Wetherby allow you into our County) and far Northerners (Scotch Corner Customs for you).
Good size runway, ample hardstandings/disused runways for car parking/static aircraft, excellent local breweries and the Northern HAS site a wow for the party!!
