All correct. Ed was an optometric physician specializing in diseases of the eye, long retired. His back has been a problem for several months. Happily, he just completed a marathon bush stint, filling buffalo full of arrows, so at least he got that work and fun in before the back got him down and now he can play with the data while recuperating. He also has another piece ready to go with TBM, all about Tanto tips, which should show up a couple of issues down the line. He'll be back! dave
