Dad's on his own

So my sister and I will be flying to CA later this week and leaving our husbands alone with our kids.  For three days.  That's right.  Three.  Days.  Alone.  With DAD.

Our husbands are perfectly capable Dads.  I'm not saying anything that they aren't.  But for my husband?  That's three days - of school, football, cheer, gymanstics, fall festival with our TWINS.  ALONE.  Did I say that before?

That's going to be a tough one.
