To find the clubs go the AMA website
www.modelaircraft.org and there is a club finder there.
I don't want to discourage anyone from taking on a project that they want to do, but I do like to give a guy a head's up on what he's getting himself into when I can. Building a flying field is much more than just dragging out a flat place with a box blade. It'll start there, but you have to remember that just one divot or rock sticking up can rip out a landing gear or cartwheel your plane on takeoff. You have to get the ground very smooth and flat, then pack it in so it stays that way. If you have experience building roads you can probably handle it. Then you'll have to maintain your surface, either by mowing or killing weeds. That's a couple hours of labor a week to maintain a 300 foot runway after you get it built. Do you really have that kind of time to devote to the hobby and still have time to enjoy flying?
