Be as packed as you can be, as soon as you can be, because something will happen. For us, in the last few days:
I have had to work overtime every day
DD's lock broke at school, needed new lock
Yearbook deadline was announced and it's the first day after March Break, so all materials have to be submitted before we leave
DH's shorts needed to be replaced
Bills to be paid
An extra load of laundry for that "gotta have it with me" item
The battery on one car died because someone left the lights on
And who knows what else will happen!
At least we know that our gear is packed and ready to go!
