Well, could barely put the thing down to come type this post.
I'm not intending work as an advertiser here, but whoa that thing has got some good stuff in it.
I'm through about page 40 and while I haven't stumbled on anything real important that I didn't already know, I've picked up some tidbits. But those first 40 pages, man if I had those when I first started umpiring. Took me 3 years to get alot of that stuff that I could have gotten in 20 minutes.
A very nice addition to the library, if you ask me. You can either read it or get the nice diagrams that will walk you through virtually every situation you will see over the course of 9 innings. Even if you know it, its a great refresher.
Wish I could buy one for a lot of my comrades...
Problem with the 2 man system is 2 people have to know it...
