i was fishin in the mississppi r. i watched a guy hook into a flathead after a few min. of play the cat made a hard run...the guy was pulled into the river...i helped him out then held him back so the cat didn't do it again, the cat tried to and almost go us both in the river...after a few hours of battle the fish seemed to give up and came in...it was the biggest flathead i have ever seen ever! and i have seen 60lbs+ fish...as i reached for the fish it flipped hit me in the head with its tail knocking me into the pole on the dock an giving me a concution the broke the guys rod before breaking the line and was never seen from again...this spot on the river is full of big flatheads...not in a tank, but definatly an example of their strength...
