My recollection of that song involves crossing the algiers ferry to go into new Orleans for Mardi Gras day. Blackwater had come out and was playing on the radio and lots of places in NO.
I was born in Baton Rouge, and we always go back. This song reminds me of my dear sweet Mother though, as it was always on the radio when she was driving me somewhere as a kid. She liked it too. Lord I miss her!
