I am pretty sure this has been a topic before. I, personally, haven't played in Metairie much, but I know many ladies prefer to stay there when traveling (could be due to less expensive incalls but not sure)
Baton Rouge, is obviously quite active
Rarely hear anything on the Northshore, but seem to get several requests due to lack of providers out that way
I can see the pro's and cons of each city. Parking, time restraints, and convenience are always a factor. I am interested in seeing where the majority of local hobbyists prefer to play.
