S.B.
There could be damage to schools in the area and they want to wait until they are all ready. After Ike, our kids were out of school for almost 2 weeks. We were without power for 4 days but there were some in our neighborhood/area who were without for most of those 2 weeks. Just because you guys weren't hit too bad doesn't mean there isn't damage around.
It is a pain when you have to take time off that you can't really afford to take off. Sorry it's so hard on you.
