Red Bull Baylines, the world’s most innovative slacklining competition, transformed San Francisco’s iconic overhead streetcar lines into a highflying aerobatic course on a Saturday afternoon. Thousands of spectators watched as eleven of the world’s best “slackers” took to the skies above Justin Herman Plaza. With a score of 25 out of a possible 30, Colorado’s Mickey Wilson was crowned the first Red Bull Baylines Champion as the revolutionary event made its North American debut.
