Grew up hunting this way. My grandfather had all of Jerry Simmons little gadgets. We lived close to Jerry, loved going by his “shop”. We setup up lock-ons with pre-drilled holes, and carried a bag of “steps” everywhere for climbing. Only problem was getting the adults to drill the holes closer together for the kids. They would drill them too far apart sometimes and make the step too far. The closer the step the safer.
