Does Sam go to every beer/homebrewer festival that Dogfish Head is a part of? The Indianapolis Homebrewers Festival is coming up in a week and Dogfish Head is on the list to be there but my friends and I all agree that it will only be a truly successful trip if we get to shake Sam's hand and taste a 90 Minute poured through Randall the Enamel Animal.
DFH is scheduled to be on-tap at The Oregon Brewers Festival 07/22/2010-07/25/2010. I just posted on the DFH FB page a few minutes ago with the same question you asked in this post. I'm going to bring my copy of "Brewing Up a Business" for him to sign. :)
