My son's best fish was about fifteen years ago. He was float tube fishing for bass in a watershed pond, using a Deep Down Rattlin' Fat Rap. He got the only crappie we ever caught out of that pond, a 3.5 pound white.
My biggest was an 18 incher, fishing Ft. Cobb Lake out of a float tube. We didn't weigh him, since we only had a tape and no scales at the time.
