Haha yeh, you "need" them. You arent likely to get asked for one to be honest so they dont even matter. But this was in a pretty busy place in Devon where i went on holiday in like 2005 or something soi needed one.
Weird as it sounds, despite having never been fishing in my life or ever having a desire to do so, looking at pictures of blokes holding massive fish as if they were puppies is one of my favourite things in the world.
