there are many good prizes for just entering a fish. If you caught a keeper, I'd enter it in the derby. May not win the top three prizes but $30,000 buys a lot of prizes besides the top three. But hey, every fish you throw back increases my odds so.....yeah, anything under say 15 pounds I'd gently release.
Wish you luck tomorrow, hope an iceshanty member wins and remember to tell the weigh in people you are an iceshanty member for our prize!!
