It was already hitting CA last Friday I remember as I leave town every week on Thursday evening mostly and I was sitting outside on the patio relaxing last Friday and I was told by a friend to get inside my room that they had been inside all day due to the radiation hitting CA for what was supposed to be 7 to 8 days startig last Friday. I do not worry about it IMO it has to be trace amnounts here however it is dangerous in Japan.
