Lots of them.
There are all kinds of airparks around south FL, almost too many to list. I know a bunch on the east coast. I am at FD88 Aero Acres outside of Ft Pierce. We have a paved runway, as well as grass, prices are more reasonable than further south, and traffic is not too bad here. There are lots and houses available. The HOA is pretty reasonable here, another important consideration when looking at airparks. There is also Treasure Coast airpark and Naked Lady Ranch just south of me. Vero Beach has Indian River Airpark. Outside of Okeechobee are some real bargain airparks, some are on the Kissimmee River as well, offering boating and flying, but you give up a certain amount of civilization for those. West Palm has Wellington, Willis glider port, and a couple of others. Jupiter, just north of West Palm has Tailwinds - pricey. West Palm is pricey. Down in Del Ray is Antiquers Aerodrome.
These are just a few I have listed, mainly because I know people at most of them. PM me if you want to chat more. I think the winter up north must be driving people down here, the traffic of people looking at properties has literally exploded in our neighborhood lately.
