Pah! Shotteswell isn't invisible, but then again, I would say that because it's but a matter of a few miles south of my house.
But anyway...
Sage advice time, esp. for low-wing pilots.
"If you can't see the airfield, you're probably flying over the top of it".
Try the Clacton farm strip course on the Cub. Really hones your airfield recognition :-) Oh and I hear stiknruda's home strip is hard to see with just a few pilots landing off a bit off strip...
