I feel bad for the kids.
It has been 11 years since I was a Little League President, and it was tough then for some folks to prove where they lived. We had a lot of renters, and many of them had a PO Box on their Driver's License. Some utility companies, because of security concerns, not longer put the service locations on a bill. Schools are open enrollment, so that is no help. Some people just don't have 3 pieces of acceptable proof of residence.
And in one case, I had 2 kids, whose parents were divorced. They had NEVER lived in league, and neither of their parents lived, or had ever lived in our league. The family law judge decided to order that the kids play in our league, because it was halfway between where both parents lived. Little League didn't want to issue a waiver until the Judge called and asked them for the name of the person to put on the arrest warrant for contempt of court. Poof, suddenly I got a waiver.
