We have a winner!
The correct answer to "How much did UAB bill Blue Cross Blue Shield for Jeff's stay?" was $557,501.66, which means our winner of the quilt contest is Susanna Leberman, assistant archivist at the Huntsville - Madison County Public Library. Her guess: $550,013. Well played!
Susanna works on the same floor of HMCPL as I do, and has followed a lot of my quilts from beginning to completion. Since she works in the library archives, she has a strong interest in historical preservation, and says that she didn't get a quilt when she got married ten years ago.
Thank you, all of you, for helping turn $557,501.66 from a jaw-dropping, heartbreaking number into something that has good connotations for me, for Susanna, and for Jeff's family. I could TOTALLY be convinced to do this again when the HealthSouth tally arrives. :)
For those of you more mathematically minded, I'm going to work up a graph of the guesses, sans names; I found the distribution quite interesting and I think you will, too. I'll get it put together in the next few days.
