Yeah, the show I saw had us under a foot of volcanic ash. I think it would actually be better on the west coast, the prevailing winds would carry most of it east.
I also saw as a kid that even though I grew up in the middle of nowhere, we are smack between 2 of the top nuke targets--Omaha for the communication grid, and Colorado Springs for Cheyenne Mt. I'm not old enough for the duck and cover drills, they figured that was a futile exercise.
No wonder I was all verklempt about looming disaster as a 4th grader.
