There's not a lot to hear minus Snowbird MOA and a few training routes. I heard a jet check in with Atlanta on the Sugarloaf RCAG a while back on 281.1 so make sure you have UHF ARTCC in your scanner to give you a heads up to activity (be aware though, mil air does sometimes use VHF). I have a word document I found a while back, but haven't had the chance to listen in and see if it's legit information/procedures for Snowbird.
Oh, and don't forget about the AR tracks too.
