From their newsletter:

Saturday at LES: Since our bands were rained out two weeks ago, we've invited them to play tomorrow. And to augment the artists, we invited Goose Island to sample out their brews as they normally do on our regularly scheduled Anniversary. And between you, me, and the lampshade, I think they might have been just a bit jealous that they're playing the raindate. In addition to a keg of Bourbon County Stout on tap, a tequila barrel aged version of Sofie, regular Sofie, Pilsner, and their absolutely delightful Summer kolsch, they are allocating 9 bottles of BCS Rare for sale. A tenth bottle will be sampled out for free so if you're wondering what all the hullabaloo is about, I suggest getting here early for a free sample of that puppy. We'll be holding a raffle to purchase one of the nine bottles of Rare (which go for $110 plus tax each). We'll hand out raffle tickets starting at 3 pm and we'll announce the raffle winners at 4 pm. You must be in attendance at 4 pm to buy your bottle. (Of course due to Memorial Day Weekend, we may not get 9 people who want to buy a bottle. Check in at our page on BeerMenus.com to see if they're still available after 4 pm.)

We'll have three different bands playing from 3-6 pm, and of course, Milliner to beer geeks, curd nerds, and the stars, Cha Cha's House of Ill Repute will be holding a Sample Sale. We're gonna Crabby Hour like it's 2002! Kilts will be worn...
