Saw about this online, just think: the wedding you've been planning for a year or two is suddenly stuck in the middle of a hurricane............venue gone, can't reach anyone. Out of town family can't get in. Maybe your house, or parent's, or groom's is gone.
I give The Knot props for this. You can get in touch and donate items, talents (saw a caligrapher on there from Michigan)
