You may want to research and see if any uncontrolled GA fields are
for sale by the state to get them off their books. A pilot I work with
bought a paved strip with buildings and things for 210K$ from the
state of California and is now semi developing it for home sites.
Check with the state DOT and go talk with some airport managers. Put
out the word you got cash. Tell them your plan to build a Soaring
mecca that will attract money and employee 100's. They would probably
loan you the money interest free.
Think outside the box and sell the idea. GA is suffering due to gas
price, alot of county airports are on the edge and the City/County
Planners want out.
Find the airport you like and if it looks unkept as if a budget cut
swept thru, that's the one to target. Bring a bank check with you for
$100K along with references and you may just be in the glider business
sooner than you think.
