Just standing behind a table just serving beer isn't as much fun and mixing with the crowd serving beer from your Proton Pack. My club, the South Omaha Brewers (SOB's), spent a couple months planning this. We had four proton packs built by one of our club members who did an awesome job. We served 19 beers at this fest on Saturday night. Great time was had by all.
Here is a dark photo of the Proton Pack itself.
