Today is the Parade Solidarité Sida (solidarity against aids in developing countries). Bastille was heaving with people, and crowds were still pouring out of the metros.

It'll be interesting to see how many people they think attended, since I've never seen so many people turn out for a march in Paris. I only really saw the start, but the parade follows 40 different live artists through the route, going from Bastille to Invalides.
