If you live near Wright Patterson AFB Area A, there is a parking lot outside of the base between gates 15-A and 12-A. This lot is huge and they have cones all over the place. It's off base so non military can still use it (near Hope Hotel, SR 444 and SR 844). Not sure what they are used for, but i just put them back when i am done. I can give you better directions if you need them.
