Look I live 'ere. It's Surrey. Right? Sez me. So there!
(...despite the hidden sign beside the A22 in Kenley that says "Surrey" - that border must also now be wrong according to the Boundary Commission or whatever the department is called...)
Saw the same question on Flyer; never knew about the strip at Woodcote (SW of A2022/A237 roundabout) - I live about a mile from there. I reckon a flexwing microlight that used to buzz round sometimes in the evening was operating from there. Might be out of use now, looks a bit unkempt on Bing.
