I called every grocery store in Marietta, Kennesaw, and Smyrna trying to find a whole packer. I ended up going to Buford Highway farmers market and they had multiple of them. It's Choice, and I paid $4.29 per pound, but I was able to get it...and I think they consistently stock it.
I'll cook it in the next few days and likely bring a chunk to AOP for those who venture out on New year's eve for Sam's break in fun run.
