I was out at cracker bar on monday with a buddy, and we landed a silver that was soo fresh its scales were still on. I believe that the bulk of the runs "chum&silvers" have yet to make it up. I've seen some old fish from both salmon, without a good rain you may not get too far with your derby. Hope it goes well, cross your fingers and hope for it. I also saw two people pull their limits out as I walked down to the cracker. All silvers FRESH fish. Maybe I could be wrong, about the statement above, but you could add silvers into the derby as well. There is a good supply of them in the river. J.C.B
