Another thing you don't see in St. Louis

We went to the neighborhood park the other day (<0.5 miles from the house) and we saw this little guy. He was running around outside the fence around the park. It was one of the wild pigs that had come down from the nearby mountains looking for some food. He was the first one I had seen roaming around. I think he probably smelled the grill from some people who were just finishing up a picnic of hot dogs. I dunno, are pigs cannibals??
