I saw one huge water snake climb up the barn door and disappear. I didn't go back into that barn for months because I knew he was in there. This was a BIG snake at least 4' long and 2-3 inches around. I'm shivering just thinking about it again.
I yelled for my son to come and help. He came, took one look at the snake and disappeared. I kept calling him but no luck so I finally went into the house. When he came down the stairs I asked why he didn't help and he said he was looking in the encyclopedia to see what kind of snake it was. ;-)
