The beer drinkers' delight opened its 17 day run today when the Bavarian Summer Festival stages its annual tapping of the first keg. The festival, one of the biggest tourist attractions in Pennsylvania, is more than a big beer party; it is full of fun, music, games, food, and entertainment. Billy Carter, the President's beer-loving brother, was in charge of tapping the first keg to officially launch the festival. An added feature this year is the world-famous Clydesdale horses of Budweiser.
