PHILADELPHIA (CBS) — On any given day, if you stop by the Art Museum steps in Philadelphia, you will see many folks doing their best Rocky impersonation.

However, some ATV riders decided to create their own version of the “Rocky Run” up and down the steps of the Art Museum early Tuesday morning.

With the season’s first considerable snowfall, a handful of riders broke out their ATV’s and rode up and down the Art Museum steps.

CBS 3 cameras just happened to be at the Art Museum as the riders went on their adventure.

Of course, riding an ATV up and down the Art Museum steps is illegal and police would certainly not be happy if they spotted the riders.

In addition, the tires of the ATV’s could damage the historic steps.
