Wow, Bryan Berg is a cardstacker extraordinare, to say the least. Here is brief bit from his bio:
Bryan Berg broke the Guinness World Record for the World’s Tallest House of Cards in 1992 at the age of seventeen, with a tower fourteen feet, six inches tall. His latest record-holding structure in the category is over twenty-five feet tall. In 2004, Guinness created a new record category for the World’s Largest House of Cards to recognize a project Berg built for Walt Disney World–a replica of Cinderella’s Castle. He continues to hold both records.
