I just got home from training and this HUGE snail was on my storm door to greet me. I tried to pry him off and put him on the lawn, but he really wanted to stay there and if I would have pulled any harder than I was I probably would have popped his shell right off. Nobody likes a naked snail. Naked snails don't make very many friends. He actually did a very nice job of cleaning a half inch wide and 4' long portion of the window.
