Our local umps attend "free" trainings in the spring before the local seasons kick off. They're encouraged to attend the state clinics, but they're not mandatory if all they're going to call is rec ball.
Fortunately, the free trainings are quite good, as the trainers are solid, national level umpires who know how to teach.
As for tcblue13's question, I agree with Steve. Call Phil. If you need his contact info, let me know.
