Being on the tightrope is living. Everything else is waiting. In 1978, at the age of 73, the Great Karl Wallenda took to the highwire for the last time. Ignoring the pleas of his family and the howling wind, he insisted on performing the grand finale to his legendary career: a solo walk on a wire strung between two buildings, 120 feet above the busy traffic and crowd below. No net. Tightrope is an interactive biography experienced in the first person. Karl’s life is in your hands.
