thanks for the advice Chief.
As for the city stocking it was my assumption. i went to hickory 2 days in a row the first day the pool had no fish whatesoever. the next trout had been stocked but there were also five or six of those big goldfish and probably another five koi mixed in with the freshly stocked trout so that was my assumption. Plus the ones in clarks spring (big spring park) do wash thru town past caseys road and race, pass the jail, and on to hickory. so my info is all based on assumption.
