Maps of gliding clubs (specifically near Chicago)

Hi,

The British Gliding Association has a list of their clubs displayed on
a map (at http://www.gliding.co.uk/findaclub/ukmap.htm).

Does anyone know of similar maps for other countries ?

It took me a long time to find gliding clubs in Poland and then it was
difficult to determine how far they where from my hotel (excellent
list of world clubs at
http://www.esgc.co.uk/home.asp?start...country=poland
but no map). I ended up having to ask a local which was the nearest
club.

I want to fly in Chicago shortly and the Soaring Society of America
list 8 clubs in IL. I will have to determine the address of each club
and find them on a map related to where I am staying. This takes time
and I am sure that many people would have done this before.

I dont mind doing this once if the data that I find helps other
people, and therefore I can use data that other people have found.

If anyone knows of such maps, I would be very greatful.

Thanks in advance,
Rob Sharpe (England)
