Video: Thousands do yoga in New York's Times Square One of the busiest crossroads in the world came to a standstill as yoga enthusiasts took over Manhattan's Times Square to celebrate the longest day of the year. The "Mind over Madness" event on Friday included free yoga classes all day. The event, in its eleventh year, saw fifteen thousand people register to roll out their yoga mats and join in. President of Times Square Alliance and co-founder of the event Tim Tompkins says part of its appeal is finding stillness and calm in the middle of the city rush.
