My family and I are coming through New Orleans to Seagrove next week and are unable to locate highway conditions, specifically across Lake Ponchetrain and along the Mississippi Coast. We lost my grandmother's home on the beach during Katrina and want to go through there for sentimental reasons. I have had trouble with some of the on-line maps being accurate before and am wondering if anyone has been this way or has any advice. I would greatly appreciate any help that is out there. Thanks, Steph
