This has happened to me twice now. It is downright embarassing and I feel like an idiot.
One time a massive hit then nothing, make another cast again another solid hit then nothing.
The another time I actually fought the fish for a minute then phooofff! gone.
Both times after retrieving the plug I reach down in the dark and feel for the hook, expecting a tacky poik!, instead I feel a dull plastic tube. You might have heard an explective being shouted off in the distance that night.
One thinks that as one gets older and more experieced he gets wiser. As I have demonstrated, more then once, that is not the always the case.
