Because it's on the West Bank, Alla is one of the few "neighborhood" parades left. All of the other parades in Orleans and Jefferson parishes have been forced onto more-or-less "standard" routes. Gone are the days of Pandora and Hercules in Metairie, Endymion by the racetrack, Pontchartrain in Da East, Helios and Zeus on Metairie Road. You can't force a west bank parade onto St. Charles Avenue, though, so Alla keeps the neighborhood flame alive.
It's all about politicians and their old-time cars in the lead. The late Sal Liberto, a Constable for Parish Court in Jefferson, always had an antique cop car he'd put in the Jefferson parades. The car (and the constable's job, for that matter) are still in the Liberto family, and a number of other pols have followed suit.
The best place for a fire truck on parade day is in the parade. If they're needed, they don't have to cut through the parade, they just have to leave it.
Shriners and their motorcycles and dune buggies! Note the two NOPD officers behind the dune buggy. Da Police are back to wearing their traditional light-blue uniform shirts. After the storm, to eliminate any confusion from posers and the dozens of cops who left town never to return, NOPD switched to an all-navy blue uniform. Now the classic uniform is back.
Alla is an interesting parade from the perspective of law enforcement. It starts in Orleans (Algiers), then moves into Jefferson Parish when it hits Terrytown and Gretna. We caught the parade early in the route, on Gen. De Gaulle in Algiers, hence the NOPD supervision.

LA National Guard. Notice they have a boat. Not very useful in Iraq, but wicked practical for storm relief efforts at home.
West Jefferson High School's AFJROTC unit. Gotta have color guards up front as well.
These folks were cool.
The Captain!
Maids of the Court. These are usually teenage daughters of members of the Krewe. 
A mounted group dressed (sort of) as Indians. 

Da Saints! Even before the days of celebrity kings and grand marshals, neighborhood parades would invite a few of the football players to ride in their parade.
Since my kiddo is a band kid nowadays, I'll do a separate post on the bands following this one.
