I purchased copy of John's 245 Ball run when I was at Valley Forge. John told me to go to a particular dealer. When I got home I found that after a few minutes the DVD would freeze. I contacted John and he was very helpful. He explained that the problem existed with only a few DVDs. He watched a new DVD to make sure it worked and sent it out to me. I wish more businesses would be as helpful and friendly. So many places would make you go through the trouble and expense of sending back the defective DVD. I realize that some people try to scam a free DVD or whatever the product is, but John was trusting enough to take my word. A true gentleman. A good business man.
