pittsburgh: I heard September 24th and September 25th, President Obama is going to come to Pittsburgh. So what is going to happen? Is there going to be mobs of people downtown? I am worried because I heard the buses wont run and they will affect people getting to their jobs? How am I going to get to my job when there is going to be a lot of security blocking my building? The president is going to be doing a lecture there where I work in so what should I expect? And what exactly is a summit?|||You are right to worry, things downtown will likely be screwed up. Try to find out in advance about the buses, and leave early. A "summit" is just a fancy term for meeting with other important leaders.|||some protesters
