Jupiter Farms since 1987. One of the few conservative leaning areas in Palm Beach county. Almost built out, prices through the roof, you might still find a 3/2/2 for just under 500K, but homes are selling fast. Still a nice area to live in if you don't mind some dirt roads, well, septic, neighbors might have horses, some have a few cows and miscellaneous other "farm" animals. Unincorporated Palm Beach county, just south of the Martin county line. When we moved here, wife called it the last frontier before the concrete jungle of south Florida, still is. As flashooter mentioned, Loxahatchee is an other good area, basically the same setting, Calusa is another one.
We are 10-20 minutes from 2 WMAs, more further away, about 15-20 minutes from saltwater boat ramps, good fishing, good diving, brand new shooting facility basically between Lox and Jup Farms that is to go out to 300 yds, skeet, trap, sporting clays, several LGSs.
