Man, everyone on earth has a picture of themselves running up those stairs like Rocky- it should be named the State Cliche of Pennsylvania. I was there last week, and my friend insisted on such a photo... in the two minutes it took us to take one of another pair of people and have them take one of us, I literally saw six other groups do the same thing. It was ridiculous.
Yeah, anyone who visits Pennsylvania for the first time is pretty much guaranteed to have atleast one of these 5 things featured in their pictures by the end of their trip:
The Liberty Bell
The Rocky Stairs (I guess, I only saw them once personally)
An Amish Horse and Buggy
Anything Reguarding Hershey's Chocolate (hershey park, chocolate world, etc)
The Battlefields/Memorials of Gettysburg
