Christine Jensen in All About Jazz:
So I actually arrived in Paris quite exhausted from the previous few months of work. I got there and this woman said, “The Place de la Seine is going on,” which is where they dump all this sand on the main thoroughfare running along the Seine. No traffic goes on it, it's all pedestrians. They put beach towels and chairs and sand and they have volleyball and all these sports going on. It was literally outside my door.
I hadn't experienced Paris in the summer before, so I just landed in this building right on the edge of this. I was like, “What is going on down there?” It was this huge extravagant party for the public along the Seine. So that was my “Promenade.” Also, for a couple of weeks I was walking miles and miles every day because there was so much to take in that way.
