Query: Historically Invaluable

For anybody with a genuine interest (ie. any adult invlolved with the LL program) this is an invaluable lesson in what LL is supposed to be. Carl Stotz tells the story of the first 12 years of LL. The man was passionate about his creation, although not for where it headed as he gradually lost control of the organization. The program ideals are the strength of LL, which Carl fully understood but had trouble getting others to see.Carl passed away near the completion of the book. Kenneth Loss, a longtime personal friend of Carl's writes well of the last few years of Carl's involvement before leaving out of frustration.As a dedicated LL coach and umpire, I could imagine how Carl felt in those early years as the program grew and thrived, and most importantly, what it meant to the boys who played.I would recommend this book to anyone involved with the LL organization, at a minimum to serve as a reminder of what the program is supposed to be and primarily, who it is for.
