There's trout in every river in the land mate, but you are right, got a find them. If you know what you are looking for you'll spot a rise or boil, whereas if you don't you won't. Us purists use dry fly and nymph. Heathens use more agricultural methods like worms and maggots and bread and minnows and spinners and,and,and. I guess they catch more though lol. It's bloody good fun whatever. Jok.
