I too, love fishing from the boat in the rain, especially a straight up and down, big-drop rain like this;
It was wild. At first, it sounded like a river in the distance, then it sounded like the river or waterfall was getting closer and closer then it poured, no wind, just slick water and you can see it hitting the surface of the water. I always do better fishing in the rain than on sunny days. LOVE IT!, and will be doing it tomorrow and the next 3 days.
