I'm not sure, Inc., except I don't think it was anything quite as interesting as a snapping turtle. We were on the Mississippi river bank at night and we would wade out a bit, duck under the water, grab a rock and let the river current flow over Us. It was a very dumb thing to do yet, it was quite exhilarating until I stepped on something extremely sharp. It's odd too that, as mentioned above, the cut didn't hurt too much, until later.
