Hi! I'm Adam Parsons - a fishing enthusiast. I have been fishing for more than 15 years now and I still strongly remember that the toughest part for me was during the learning process. Most guides I read during that time was too technical to understand. Therefore, I make sure that everything I post on dream-guides regarding fishing is written well and easy to understand even if you are a newbie.
