I was looking at the info on MassWildlife on the pond map the other day and they called that out:
"This pond has a reputation as a good bass producer, however, and numerous large bass have been reported as taken here (including the state record, but that fish based on numerous reliable reports actually came from another pond)."

Any idea where it actually came from?
