It comes to mind that the OpenAMA club wont be charging the ParkieAMA members anything. The Parkie members will pay their dues to the ParkieAMA Club, and the ParkieAMA club has to pay for access to the site. This is a landowner deal the ParkieAMA Club will have, not a deal with the OpenAMA club....

...unless the club is the landowner.
Then the landowner (OpenAMA club) will be charging the ParkieAMA CLUB for access to the site like any other landlord would do. They dont put a Per Head rent, they use a Per Month or Per Year. So the ParkieAMA club will have to pay the $XXX rent no mater if they have 5 members or 50. If you want to develope some Per Head landowner rent for this discussion, ok, just say so & we can run with that.

Obviously if the site is developed into a fine flying field it would command far more rent than a pasture that needs $4000 of work for parkinglot runway & tables/pilotstations.

Of course there could be a setup like Tyler, where the ParkieAMA club would just be #3 club at the site and the deals will be with the city for use of city property. I dont know how hard it will be to get the city to give more urban park land to ParkieAMA flying clubs, since they already have a muni RC Flying Park and have city RC laws on the books. It could very well be that the AMA clubs have made Tyler unfriendly to urban PF flying... or not, dont know, I'm not on their city council
