I have been to Harry's School, its a great school and you learn alot but I have to agree with mazzamouth statement. At Harry's you work with the MLB guys 85% of the time and the Minor League Umpires the rest of the time. I have friends who have been to both and I have friends from both schools in the Minors working. From talking to them and talking about how both schools are conducted you seem to get more from Jim's school because you have more Minor League guys working with ya! Just my two cents...
