drafter,
I heard about the ice jam and there were some e3vacualtions. They can be scary. When I was in Nebraska they had a guy that would drop dynamite from a bridge to break up the jams. He had quite a reputation and I met him when he was an old codger. He caught me staring at his missing left hand. A big smile came to his face and he said, " That's what happens when you hold onto a stick of blast a few seconds too long."
BTW, nice to hear from you drafter. It is nice to have folks with the same interest in the area.
