I took over a dozen snakes to a few high school science classes and gave discussions on genetics. I was shocked. The vast majority of the students were absolutely fascinated, and most wanted to hold a snake. I bravely passed the more docile ones around the class, and was lucky to get them all back. The kids went home wanting to go to the next Repticon, which I told them about. I had one girl utter several 4-letter words and cower in a corner. When it was all over, I almost had to pry a snake out of her hands as she talked to it like it was a little puppy. It was nice to have changed some attitudes, but even nicer to see how few needed changing.
