We all have encountered all those big black balls of shad in early summer, migrating out of the creeks heading to deeper water and again in the fall heading back into the creeks. When the fish are keyed on the shad they are tough to catch. While spinnerbaits are a good choice to catch these fish, I've found that a rattletrap is more reliable. When you see these schools burn a 1/4oz trap through the middle of the school and kill it once the school starts to scatter. This will draw a strike from even the wariest of fish.
