Hey Steve - Ditto. Maybe a group of us could contribute to a book on some of
the silliness we run into in the name of Engineering and profitability. You
couldn't dream some of this stuff up. It would make a good "Electronics
Manufacturing Comedy Book".

Along with everyone else, I am really curious why "they" want to do the gold
on the populated board. I'm staying tuned in for the answer.
