Wow I was a fan of Farrer pond. I personally witnessed an 8 lb Largemouth pulled out of there. IT was 22" long. My friend was using spinnerbaits.
Anyway I called the state about it's closure seeing how it was technically a "Great Pond" which means over 6 acres (??) Turns out the pond was grandfathered since it was man made back in the revolutionary war era. So it could be posted. I've caught what looks like Northerns in there too. There is a flood connection through a creek to the Sudbury river so it wouldn't surprise me.
