At less than 1,000 feet agl, we had little time to begin setting up the aircraft for an off-airport landing. I picked my spot in the field where I wanted to touch down, hoping, if I made that spot, I could stop before we got to the fence at the other end. I held airspeed while setting up for a left downwind to landing. As I came abreast of the end of the field, I turned onto a descending base leg, and that's when I saw the high lines. All I could remember was what my good friend and instructor, Bren Slaton, always said when we practiced this or any other maneuver: "The three most important things in flying are ‘airspeed, airspeed and airspeed.' If you have airspeed, you have a lot of options. Without it, you have none."
