... assuming your plane/s last long enough for you to get good, and then you go to a new field and suddenly you're nowhere near as good. I see it all the time where I fly - we have a main runway with two diagonal runways running off it (like a letter K where the vertical's the main runway) for when we have strong cross winds. I, like most members of the club, can put my plane down in the middle of the main runway with my eyes closed, but put me on one of the cross runways and I blunder about, often finding the longer grass at the edge, or trying to put it down 2/3 the way along the cross runway. I actually prefer to land on the main in a cross wind than use the cross strips. (Hmm maybe I should rebuild my old trainer and practice cross strip landings.)
