I lived in NOLA for about 3 years and rode a bike there. There are not hardly any messengers in that city. I don't think there are any. Besides that, it is really tough to get around on a road bike because the streets are SO bad. There are potholes and debris EVERYWHERE. Maybe there are a few messengers, but I really doubt it. Especially after the hurricane, there isn't really a need for them. I agree with what was said above, if you want money and want to pedal, become a pedicab downtown. Just be careful late at night, you WILL get jacked. 3 of my friends got mugged and my roommate got his car stolen while we lived there. I got the hell out, that place sucks
