Perhaps I should have said “GENERALLY I can see nothing wrong with mnemonics”.  I must admit, I didn’t look at the tattoo closely.  I thought most of the subsequent discussion was just light hearted banter.  My comment re tending to agree with Frank referred only to the fact that I’ve never felt the need for a little ditty to remember whether to plot PLs towards or away from the assumed position.  You were correct on taking me to task over the tall building thing. The light rays from a star can, of course, be taken as parallel anywhere on the Earth. I was just trying to say that, geometrically correct or not, it seems intuitive to me that if you walk towards something it appears to me to get higher in the sky, so that’s the way I remember it.  If you want examples of explanations which are neat, plausible, and wrong, but have served reasonably well for years, look at some of the simpler examples of how an aerofoil produces lift, but let’s not go down that road.  The one   thing you didn’t answer was where and why I learned “Late Back West”.
