I almost stepped on a Boa Constrictor. It was Huge. Here we were, innocently walking along on this nice path covered with dead leaves and things in the Atlantic forest-y zone of the University when I noticed something that was basically right under my foot (OK, it may have been 3-5 feet away but in the moment, it was really dramatic). We were wearing boots, so it wasn’t too dangerous, but I don’t think I’ve ever seen a snake that big in the wild.
