I used to fish for them a lot when I was younger and lived in Western MA near the CT River. I used wheaties mashed up and mixed with strawberry soda on a small hook and slip sinker. It was not uncommon to take several over 20 pounds on a given outing. The state record is 44 pounds, landed in the CT River. This one should blow your mind though...
