There is a Facebook Group "Slide Rule Fan Club" that links those of us who collect rules. 
Maybe we have already seen each other's posts there? ;-)

During my satellite presentations, I will ask attendees to access their 
slide rules as we together derive satellite pass data manually, to graph 
each pass on equatorial graph paper …

“What - no one has a slide rule?” I will playfully chide them. “Didn’t the 
club president tell you all to have him for the presentation?”

Well, the Puget Sound Repeater Group just floored me: EIGHT SLIDE 
RULES were in the audience (three from one person, including a 
circular one and I recognized another as a Pickett Vector Model 300 - 
in its original leather case)!

A wonderful club. Sixty-two total years of supporting their region. 
Multiple daily nets that are well-attended (I know - I monitored ‘em 
via Echolink for a couple days). ARRL Special Service Club …

And very exciting for them: a 89-degree elevation pass of the ISS 
this evening during their 9PM Net!

I lost count … I think this was the 144th or 145th show presented. It 
is not getting old … as long as clubs want to know how to work the 
"easy” satellites, AMSAT will get the information to them!
