By Abigail Scott
I'm Abigail Scott, an author, adventurer, and mother of three. When I'm not navigating the beautiful chaos of motherhood, you can find me tackling the turbulent waters as a professional whitewater kayaker or scaling impressive rock faces as a climbing guide. The rush of adrenaline, whether from kayaking or climbing, is a feeling I cherish deeply. But the thrill doesn't stop there; I capture the breathtaking allure of nature through my lens as a professional photographer. And when I'm not submerged in the wild, my software engineering skills amplify my outdoor pursuits, allowing me to harness technology in unique ways. Through my writings, whether articles or blog posts, I share not just my adventures but my heart, hoping to spark a flame of inspiration in others to break boundaries and experience the world's wonders.
