Now that I think about it more, I am not sure I have seen one looking like a spotted cow. I think I have just seen ones with maybe 1 black patch or have the body is black.
The cool thing about fishing is sometimes it is not about the most fish or the biggest fish, but instead discovering something you never saw before.
I wish we had a thread pinned dedicated to unusual fish we caught or unusual things we have seen while fishing. I thought we tried starting one a year or two ago that began by someone posting the humpback saugers in the Mississippi.
