I just checked my copy, the last one is #83 dated in 1995. In the very last paragraph, Fred is saying that this is the last copy of his newsletters.
I have newsletters #1 thru #82 in two Zone VI 3-ring binders, my subscription ran out @ #82, I missed the last issue. What did I miss in terms of technical info or technique - or was #83 just a farewell note to subscribers?
