We had a 6 foot corn snake living in our detached garage for a while. Every now and then we would see a smaller (3ft) one coiled around the top of the bird feeder. I never wanted to pet them, but they were cute and we felt bad when they disappeared. It doesn't surprise me though that someone who lives where corn snakes do would pick one up. They aren't shy about being seen, as snakes go, and they're pretty docile.
