Yah i have heard about the Susquehanna and all the people. Good thing for your friend and those poor people, its all just so sad. I live in PA, and have been to Harrisburg and Hershy, its so unbeliebable that this happended to them.
I heard that they had been evacuating people along the river and that they where shutting down the briges at one point as well. They even where transfering patients from hospitals as well. I just hope that this is the end of the rain for them.
Just google or youtube it and you should find some things about it.
