Jeremy awesome report! Brings back memories, would love to see that fishery recover. 18.5" is a beast of a winter flounder. Slow moving retrieve like you did or bouncing it under a boat while chumming are the best ways to catch winter flounder. Nice job. Some good looking bok choy, must have been a great meal. Winter flounder make a great meal, noticeably better in my opinion than their summer cousins.
