Growing up on Long Island in the 1980s, Steve Trebing and his friends had two remarkable talents: avoiding adult supervision and turning terrible ideas into unforgettable memories. In Lessons from a Knucklehead, Trebing revisits a world before cell phones, GPS, and helicopter parenting-when kids disappeared for hours, built forts in the woods, and somehow survived decisions that probably should've landed them in jail. At the center of it all is The Septagon, a hidden, homemade fortress built from stolen scraps, questionable engineering, and pure teenage determination. What follows is a nonstop string of adventures, misadventures, and near-catastrophes: a bicycle trip, a reckless scavenger hunt, run-ins with the police, and enough bad judgment to make every parent in America nervous. Alongside his loyal band of co-conspirators, Trebing captures the chaos of growing up in an era where freedom came first, and consequences usually arrived later. The stories are outrageous, hilarious, and just self-aware enough to admit that almost every mishap started with someone saying, "This is a great idea." But beneath the laughter is something real: a snapshot of a disappearing childhood-one filled with scraped knees, dumb risks, loyal friendships, and the kind of adventures that can only happen when nobody's watching. Funny, nostalgic, and wildly relatable, Lessons from a Knucklehead is for anyone who survived growing up before common sense, social media, and parental tracking apps ruined all the fun.
