Also sending this out in case it affects anyone's parking and/or travel plans on Sunday, 9/1/13 (or if people wish to be spectators for this event:)
The parade will start at the Old U.S. Mint, then travel on Royal St. to St. Louis St., and then do a slight bit of zig-zagging through the middle of the French Quarter until it reaches the intersection of Bourbon St. and Dumaine St:
