The Madrid Cow Parade cows were auctioned last night.

I have many pictures of the stampede as they were lined up in the street outside the Westin Palace Hotel, but no time to pick, choose and process, so will settle for this one for the moment:
Mi Sueño (“my dream”) by Carlos A González, sponsored by alimentacion.es.
And a few brief words from Gelett Burgess (1866–1951):
I never saw a purple cow;
I never hope to see one;
but I can tell you anyhow;
I’d rather see than be one!
