Penguina!!
Please write out 100 times - Bourn has a N-S concrete runway, Little Gransden has two roughly E-W grass strips.
(Although I have to confess that I've never found it either - another contender for

AB - isn't it time you bought a new T-shirt?
Whirly - short grass runways? I'm starting to like them.
