Everyone in Philadelphia loves Rocky. The museum steps that Rocky runs up are probably the most important tourist attraction in the whole city, and this is the city where they signed the Declaration of Independence. At any one time, there is always at least one person skipping up the steps and jumping around at the top.

This is Angie and Stephie doing the famous run, but you'll notice that in the original, Rocky didn't run up the steps holding his best friend's hand.
