What I find pretty cool was that John baptized in the Jordan River and Peter Fished in thr sea of galilee (its actually a massive lake) well the jordan river connects the that lake in an unconventional fashion. So there isn't a clear definition of where the lake starts and where the river ends becuase the mouth is like a marsh. You are esse tially in the lake but is pretty shallow. Another cool thing to note, as it becomes evening high winds come down from the mountains into the sea of galilee essentially making the water choppy and causing the fishermen to return to land. So when Peter was going back to land, its probobly because it started to get a little choppy but he casted a net out anyways upon Jesus's request.
