I'm originally from New Orleans, but I have admit that I'm not very familiar with the tennis scene. I have a tennis playing family so my junior career was spent hitting with multiple relatives, private coaches and playing tournaments. I honestly didn't have a need to scope out the local tennis scene.
With that being said, I know that there used to be a considerable gathering of players at Stern Tennis Center on S. Saratoga in New Orleans. Usually on Saturdays. There doesn't seem to be a lot of action at City Park anymore, but I could be wrong seeing that I only get home about 3 times a year.
