friends of mine just picked up a packer from Kroger for $2.18/lb. not the best cutting job in the world, but it should turn out well, was fresh at least.
as far as the fat side up/down, I've got a couple shoulders on the UDS now and will be doing the brisket after. I've got a 20" pizza pan I'm using as a heat defuser so I can go fat side up and let the fat render. We'll see how it turns out.
