On November 1st, Buenos Aires air will thunder with the hooves as the 132nd Argentine Open Polo Championship begins at Campo Argentino de Polo in Palermo. This isn't any other tournament. It's the final jewel in the Triple Crown, following the Hurlingham and Tortugas Opens, and the most prestigious polo competition on earth. "The Cathedral of Polo" has hosted this championship since 1928, its two pristine fields accommodating 30,000 spectators who gather beneath Buenos Aires' skyline to watch something extraordinary.
