Apparently not many physicians knew how to treat that.
Well, that seems to answer the question. Also, the fact that you remember an incident that long ago might be rather indicative of how rare these attacks are. On a lighter note, the chances of getting into a collision on the road to the shore from Tallahasee would prabably be less than that of getting stung there by a ray. It's a long drive, and I don't remember seeing another vehicle when I did it.
