Kentucky Derby devotees will surely get their fill of bourbon and mint juleps Saturday, but what do beer drinkers get? On Sunday, they get Sly Fox’s annual Bock Fest and Goat Race at its Phoenixville location. As far as good times go, it’s a no-brainer. Sly Fox will roll out an impressive collection of bock beers, including Slacker Bock, Helles Bock, Instigator Doppelbock, and two Eisbocks. There’s also going to be keg of Maibock, but it won’t get tapped until a winning goat crosses the finish line. The winner’s owner gets first crack at it, and the naming rights for it. More than 50 goats are already entered. All remaining goats must be registered and checked in by noon on Sunday. The races start at 2 p.m.
