   "They must have had some beef with each other as they completely ignored my presence only a few feet away.
   "They splashed, rolled and floated at least twenty yards during the encounter resting for a few minutes in between rounds. 
   "Note the wounds on the head, legs and throat of the combatants.  There was no clear winner as both eventually swam away seemingly unharmed.  Needless to say, this marsh championship bout was exciting to witness and photograph!"
   We are wondering if this battle may have been a question of overly amorous turtles. Any theories?
