 The Abbey Resort in Fontana-on-Geneva Lake, Wisconsin claims to have the world's tallest wooden A-frame.The post–World War II popularity of the A-frame has been attributed to a combination of factors including Americans' extra disposable income, the inexpensiveness of building an A-frame structure, and a new interest in acquiring a second home for vacationing.Another factor contributing to the rise of the A-frame included the adaptability of the structure itself, which enabled architects to experiment with more modern designs.
