I'll be in Paducah and I hope I get to see your quilt there! If UPS has it, it will be found. I hope it's nothing at fault on QNL end.
Why wouldn't UPS have a UPS employee with picture in hand go to the unclaimed items and look for the quilt? As every corp/business, it gets passed from desk to desk and by the time the one person that can help gets the task no one knows anything about it. The UPS investigator for you should get off his/her butt and start looking for themselves not depend on others that don't care anyway.
