LARGEST BASS IN THE NATION CAUGHT ON AN AC!! Don't know how to really start this one. Ok, let me try... Allan and Steve had a "lifetime" day, spanking a bunch of monster bass and setting some new AC Plug records. Here are some notables: Steve landed the biggest bass ever caught on an AC and his personal best at 18 pounds 6 ounces. Allan landed his second largest bass ever at 16 pounds 1 ounce. As far as we know Steve's fish is the largest bass caught in the US for 2006. We are hard pressed to remember anyone reporting two bass over 16 pounds caught out of the same boat on the same day.
