I was in a building when it happened and since I am in the DC metro area we thought the worst until it went on a bit longer! After living in Cali for ages it soon dawned on me what it was! Folks started to dash out - one of the few times I have seen people run out of a building so fast! I sat in my chair once I realized it couldn't get much worse! Anyhoo, we were evacuated - building was closed up the day! My bf works downtown and he had to deal w a sea of suited zombies walking about in a bewildered state!
When I lived in Cali, I once experienced a quake while sitting in a rocking chair. I was watching a landslide (some news report) and felt like I was sliding outta my chair - talk about interactive TV!!
I love my JB iPad!!
