Pedro picked us up at 7A the following morning and drove us to meet a fishing guide on the Rio de la Plata. We loaded into his boat and took a 45 minute (?) ride to our fishing location. The banks were lined with houses of all shapes and sizes. This river tour was worth the ride. Finally we arrived at our location and our guide rigged our rods, baiting them with live fish set on a very large hook! Further there was a wire leader which indicated the fish had teeth... Holy Cow, what are we fishing for! The rods were cast out and it wasnt long and I could tell something was messing with my bait. I set the hook, but it was a missed attempt. I reeled my bait in to find something had bit the tail off clean. Pedro hooked a fish and handed me the rod to reel the fish in. It turned out to be a piranha looking fish, but was not. I was told at least three times what these fish were but cannot recall the proper names. EIther way, we caught about 6 to 10 of these and had a good time doing it. Our target species, the golden dorado remained untouched. We moved to another location to try our luck there. Along the way, Pedro excitedly pointed something in the river ahead of us. I looked and saw a deer swimming the river. They were excited and my wife was telling me to get pictures. I didnt want to take my eyes off the deer but did for a moment and by the time I got my phone up, the deer had disappeared into the tules. This, I learned was the very rare Marsh Deer. They cannot be hunted anywhere in their range and are rarely seen locally. As a former biologists and former game warden, I felt privileged at this chance encounter. We tried a few more locations but failed to turn up a golden Dorado. The river was what we call in Oregon as "out of shape," meaning the river was carrying silt and debris from a runoff somewhere. When we returned to the dock, the river was 4 feet or more higher than when we left. Not good fishing conditions and clearly outside of the guides control. The river ride was worth the price of admission. Shannon told me this morning that she would like to try this again as she really loved the trip.
