Theres a pond up the road from where I live that had abnormally large panfish introduced to it quite some time ago by the land owners. The land around it was sold off to someone else and the pond was widened but the new owners had no idea there fish in it. A buddy and me asked if we could fish there and they gave us permission. We caught some nice 18" walleys (yes in a pond), tons of 17" bass...and above all else some monster 'gills. Check these things out, our Wisconsin state record is 13" and the following was 12"!!! Better yet, the smallest bluegill we caught was 10" and we had about 15 in total! This is my friend with that 12 incher...
