Jimnev,
No matter where you go you will be those that direct you one way while others guide you in another direction. The selection will come down to your son's and the family's personal preference. If I were going into a new area whether it be Florida or Washington State I would contact local college coaches and ask about summer “feeder” programs and high school programs. A good way to do this might be to set up a lesson with some of the local college coaches or attend one of their camps to introduce your son and yourself to the “baseball parents” and the baseball coaches in the area. (rest assured they will be in attendance). Good luck in your move to Florida.
