I also wrote a book about Guardian Angel. I and my 3 brothers went there for 4 plus years, 1948-1952. It is at Bosses book store in Green Bay, probably right next to your uncles. If you were to purchase my book you would also get a CD with about 145 pictures on it of GABS. There is a view from above in his book on page 22.
