We re moving from the Northeast (finally!

and have the option of either the Dallas area, or southern Ocala (North Orlando). I have 10 horses (mostly youngsters)-we want at least 10 acres (preferably mostly pasture), a horse friendly climate (little to no snow), reasonable real estate (under 500k for 10+ acres 2000sf+ house).
We would like an area that is horse friendly. I have ridden dressage, hunter, western-but mainly raise train youngsters now. We also love to trail ride.
Any input would be greatly appreciated!
