Jim Groat — “Corporal Doberman” — showed me how to disarm a tank mine with a nail.

Everybody I know is an absolute expert in something. I keep a list of supergeeks. No, I tell a lie. Any more, I just send a note out to my colleagues and readers and ask if anybody can help me out with the details. Picking somebody else’s brain — who already know all the links (let’s face it, that’s what we’ll get ) — is going to save me research time.

I’m not an expert on a  lot of anything; my memory is too messed up. Everything fades. Oh, well.
