I have been an outdoor activities enthusiast from teenage. I have been going out with my parents on different outdoor activities such as camping and hiking. After moving to a town surrounded by three well known fishing spots, I started fishing and started using all kinds of tricks and equipment to make the most out of each adventure I pursued. Over the years I have been camping outdoor, hiking and following my passion of enjoying life at full. Few years ago, I started writing about my thoughts, experiments and ideas about outdoor, fishing, hiking and more. This blog is a compilation of that plus tips, ideas and products that can make life more meaningful, enjoyable and a pleasant.
