One of the great things about Jazz Fest in New Orleans is that the people are great. Yes, the music is great, however, I think the crowd of people makes it that much more enjoyable. With more than 400,000 people over a period of 7 days, you would think people would get into the occasional squabble.
I have never seen it happen - or even come close. Everyone is enjoying the music and just having a good time.
The Fais Do Do stage is a great example. Everyone is dancing and having enjoying the music. Mostly, they are dancing with friends, but a fair amount are dancing with total strangers - like the couple in the photo. He just walked up and asked her to dance, and away they went.
As you can see from the photo, they are both having a great time. Gotta love Fest!
