Having "a couple dozen" 6.6s go off at once or even over a few days
doesn't sound too good, does it?

Not to mention I'm pretty sure any ocean hits would be Tsunami City.

This seems to be turning into just another lousy disaster flick, when
what I was really wanting to stress was the giant steelies.

Maybe we should change it to "a couple dozen quarter-mile-wide steel balls
just showed up one day around the planet" . . . .
