At work in Owings Mills, I thought a large truck was rumbling by, then I realized:
1) I am dozens of yards from the road and
2) Large trucks *never* come down my street
I was in San Francisco in 1989 for the Loma Prieta (World Series) quake. This was nothing like that, of course, but my nerves still haven't completely calmed down, and I'm not entirely happy about being back in my office building.
