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?|||By then, your employer should have all the needed information to give to the employees. For all you know, it could be an extra 2 days off from work.
