What prompts an individual to post their feelings and thoughts on a wall? Just yesterday, while riding the crew elevator in Pittsburgh, I noticed writing on the wall (large writing) of the elevator. When the doors of the elevator are open on the concourse level, it is easily viewed by the public. This is not the only place I have spotted garbage on the walls. If anyone is familiar with the "f" concourse in Philly, there is a hallway where folks like to sneak off to get a quick nicotine fix. Here is where one would find the most intelligent writings from some of the most intelligent people ever. I know that people are angry with everything that has been going on, but this is ridiculous.
