One of the things we did in New Orleans was to go on a Swamp Tour. By bus-van passed Lake Ponchartrain and then the 20 of us got into a boat. We saw lots of swamp-life: trees, alligators, wild hogs, birds. The hogs were quite netertaining. There were small colonies of houses that we passed - some not in very good condition. All in all it was a fun few hours.
