yup - one of the reasons we always took off is we had people in Birmingham and then my parents lived in Chattanooga - after Katrina (my oldest born in '08) it was always a good excuse for grandparent visit
I wish I had family in locations to evacuate to but I really don't have any family that doesn't live here that isn't too far away to reasonably evacuate other than my wife's family in Alexandria, LA, but that's not really an option for many reasons I won't go into here other than to say that they have a lot of dogs which would be a problem with our cats. My brother does have a "cabin" in North Carolina, but that's an 11 hour drive each way which doesn't really work with pets and really to far to get back in town in a reasonable amount of time after a storm if the City is fine and my job wants me in the office. Plus, we thought it was a safe place from storms until last week. Plus he rents out that cabin at times so it's not always available.
Of course, staying with family can have it's own issues and in a situation like Katrina where a couple days turned into weeks or months, it has many problems.
