I must have missed the episode where they announced him leaving.
I have to say I am often a lounge chair fisherman and am getting bored of the show, I'm reasonable new and am still looking for hints, tips, techniques, fishing times, places, moon phases etc etc etc and all of that seems to have almost disapeared from the show. All that is left is Paul laughing ho ho ho! how good is this! he says. Not really that entertaining anymore, but i'll keep watching.
