In the past, the "trophies" were largely 16 and some 17 inchers. With an occasional 18 inch anomaly. Brooders, were larger. And some were over 20 pounds.
However it's anybody's guess, this year. Because the stocking is now provided, by a privately owned company.
So by all means, let us know, what you catch. So far, the reports are mixed (on being any larger, or any healthier, than in past years).
