i didn't know jazz was a genre that originated in new orleans
Wow me either. I guess that's why everyone says New Orleans has such a rich culture.
that probably contributes to why its the largest US port and metropolitian area in louisiana
That's really interesting. Although I don't think New Orleans has much competition with other ports in Louisiana.
actually baton rouge might be as it is the parish on the mississippi river
Is that still a port though? I was under the assumption ports were connected to international waters like an ocean. 
it is the parish seat of east baton rouge so maybe a part of it connects to water maybe?
