One time I saw a guy dash down Broadway for a X27/28 (can't remember) between two of the stops. It was below 14th, where the stops aren't together. To my amazement, he caught up with the bus. Only time that I can remember running for a bus was last month when I needed the Q17 at Hillside & 179th. Ran down to 183rd and made it, only because the red lights went up on Hillside. Usually I don't run for a bus but when time is of the essence, gotta move.
