I love the concept and upvoted but I really wish there was a [USA] tag. I'm on the other side of the world and I clicked, wondering if there are any airfields near where I live. I am still wondering.
(Side note to those who might know: beyond Juhu Aerodrome, does anyone know of any other such small airfields nearby?
A local library may have or know how to get access to your areas "sectional charts" - perhaps even historic ones, which show all these things.
