I can get Surly here, and Bender is year round, but I'm not sure about Bitter Brewer. You know that Bitter Brewer is their version of an English Bitter, and isn't really a uber hopped bitter beer, right? Abrasive Ale is their version of a DIPA, and that's available right now too. I'd be willing to trade for some interesting stuff that I can't get here, or limited edition stuff. I'm mostly interested in strong Belgians (tripels and quads), porters and stouts (especially bourbon barrel aged stuff) and stuff along those lines.
I'm pretty open, so let me know if you're interested in trading.
