Gumball head is easy if you want some.
Zombie Dust is the one that requires some effort.
I don't really think it's worth the effort or the coin to be honest.
Scotty is much better connected and able to supply than I... but usually gumball head and necron 99 are sitting at my local liquor store for purchase. Crap is up to $12-14 a sixer and zombie dust might have been a hair higher if I recall.
For me... I don't make the hour drive to the brewery and sure as hell don't stand in line on release days. I think they cut it down to a case as well and cut off the bombers. It used to be $7-10 bombers at the brewery and those make more sense to ship or buy.
But if'n yer dying for it let me know. It shows up often enough that if I knew it had a home I can pick some up.
Wisconsin, Illinois and Indiana does have lots of great beer... but fer my money I'd happily limit myself to Michigan. There aren't many beers that Bells or Founders don't make as well or better. Two Hearted IPA is right up there with any three floyds stuff and sitting on the shelf. Founders does a whole series of IPA's that even a non-ipa drinker like me can appreciate in the summertime.
Had an awesome barrell aged IPA the other day.

A four pack of that is a million times better than zombie dust at roughly the same price.
Hop Slam... Heady Topper... Sleeper Cell... Dank Meme or Wake up Neo from Tryptych are all beers better spent tracking down fer your money than anything from 3 Floyds really.
