Since I was born and raised in Puerto Rico, I know a thing or two about hurricanes.
I remember David, Hugo and Georges... this last one was pretty destructive some of our family lost their houses, and where I worked was closed down for two weeks because the storm literally took part of the building with it.
It's been a while since then, and I've lived in a few places (please don't guess my age...HA!).
Having said that, if Isaac happens to pass through or close to Florida, this will be my first experience with a storm/hurricane in S. Florida. That scares me a little, since everything here seems to be built in some sort of cardboard.
