there is some intangible quality that drives us to spend hundreds of
hours and lots of money on projects that others may consider pointless,
or perhaps it’s a form of mental illness?

Yeah, like spending hours inside 2 MTC-7 shelters in the hot sun (I now
know what a turkey feels like in a convection oven), because we can't
just be happy with the display of vintage technology. NOOOOOOO, we have
to make sure all the phone circuits work too so we can make calls too...

I figure we spent about 75 hours per phone call made.
