that is a baby one, i don't particularly like them, but they have to be a little higher than 5 to wake me up. i sleep in the basement so i hear it first and the sound usually wakes me up first before it hits. dog won't wake up unless it's more than 5 either.
hope everyone is ok, oddly i was thinking last night we hadn't had one in a while, but i was thinking it when i was outside which is the worst possible place to be during one.
lexis you should come visit alaska, it's kinda cool when you are driving down the road and you see it roll in front of you
