actually it was in a pretty big lake, he was kickin it right up against the boulder/rocky shore where i was throwing flies for big bass and trout. i know they'll hit flies but it was the last thing i was expecting. thought i had a huge brown or bass on at first.
you're right bill. i was looking at the absence of spots, but several sites say that larger specimens may not have them. anal fin is the clincher from what i can find - blues have a straight one, channels have a rounded one.
