I am in Paris now and am worried about the Seine as well as the readiness of the city in general. They are working feverishly to get a stadium built in the Place de la Concorde and there is construction going on throughout the Tuileries, around the Louvre, etc. Traffic is a huge problem right now—I cannot imagine what it will be like during Olympics. The city will be raising prices everywhere (metro tickets will double from 2€ to 4€, as an example). Several waiters and even Uber drivers told us they plan to leave during the Olympics as it will be too crazy!The mayor of France was on the evening news the other night, making a cordial but unconvincing case that the Seine would be ready for swimmers.
