SOARING

Ok you’re not really a glider pilot, but this looks like a nice break from asset pricing and macroeconomics, doesn't it?

Go to the SSA (Soaring Society of America) web page to see what gliders look like and where you can try it. If you go out to an airport, say “trial lesson” and make them put you in front. Don’t say “ride” or they’ll treat you like a tourist, stuff you in back and charge you too much.

The Life to the max show video is a nice introduction to what gliding is about. More advanced flying Videos (youtube links): Aerobatics over the AlpsSoaring in Chile (grand prix footage)

I fly mostly at the Williams soaring center. I used to fly at the Chicago Glider club, southwest of Joliet.
