Rory McIlroy is out in Pennsylvania for the U.S. Open which was supposed to begin on Thursday, but due to poor weather the start was delayed. Rory took some time out of his practice schedule to do something that most folks also do when they are in close proximity to Philadelphia. Rory scaled the 72 steps of the ‘Rocky Stairs’ which are outside the Philadelphia Art Museum and snapped a pic for his 1.6 million Twitter followers to check out.
