For specific info regarding re-entry into Jefferson Parish go to www.jeffparish.net.
For some extremely detailed aerial (satelite) photos go to www.katrinadata.com. The photos you pull up are not north-up, so you must figure out the street orientation. You can actually see your home and other structures.
Marge and I are fine - in Virginia with family - and our home seems to be OK.
Our prayers are with all of you and all of the people of Louisiana, Missippi and Alabama.
