I kept the tower open an extra hour or so


Does that mean the Class D Airspace was in existence an extra hour too?

That was before they invented the lettered airspace. We were a control
zone back then.


What happens if I dutifully read my AFD and discover that the tower (and
the associated CDAS) closes at midnight, so I figure when I arrive at 12:30
I don't need to talk to anybody.

I fly in, enter the pattern, land, and taxi to the ramp without bothering
to self-announce. Have I broken any regulations?

The weather was IFR so yeah, you broke some regs. In reality we would
work around you should that ever happen in VFR weather. No rules would
have been busted.
