to the Industrial Canal were not going to be crowded with family visitors that night, maybe she could help you out. There aren't any motel/hotel facilities right around there, and I don't recommend camping on the levee, because of occasional robberies.
I would recommend you get back on Google Earth and scout the canal area from space. I'm assuming you mean the Industrial Canal. If you got through the canal first, maybe options would be better on the Lake Ponchertrain side. There are state parks with camping options, and maybe motels in Slidell, etc, to which you could cart the boat.
