Funny, I was just thinking I need to check out the local liquor store to see if the winter Folly packs were in yet. 2 Below is good, Rampant is good, Abbey is good, and Ranger is decent. The Fat Tires might sit unnoticed for awhile, but they'll get drank eventually (nothing against Fat Tire, but there are better options).
An even better variety pack, in my opinion, is Odell's Fall/Winter Montage. It includes 5 Barrel, IPA, Gramp's Oatmeal Stout and Isolation Ale. All of those are good brews and their IPA is one of the best around. I might buy one of the Folly packs and be satisfied, but I'll be buying a few of the Montage packs before they're gone.
