You can visit all over Louisiana and it varies from parish to parish.
Matt, didn't you stay in Cameron or something? Monroe?
I can't remember where you said you stayed but I know it wasn't the most pleasant of LA towns.
Its like any other State, It varies from person to person and city to city.
I've traveled to a few states and I will have to disagree with Matty about Southern Hospitality. The town in which I live, the majority of the people are friendly. I can't imagine not greeting someone while walking down the street. Opening and holding the door for people. Lending a hand in the Grocery store to the lil ol' lady that can't quite reach the Depends.
I didn't see that hospitality in the majority of cities I visited. Sure there were some, just not what I am used to here in my town.
My travels aren't vast... I'm just commenting on my personal experience.
