These guys were dancing/struggling (it was a windy day) with this sign that was festooned with all manner of iconography: riders on rearing horses, portraits of mustachioed guys slung with bandoliers of bullets, the Virgin Mary, Aztec-looking natives, Mexican flags, Spanish phrases (wish I spoke it), and a soft sculpture of a white bull with a ring in its nose at the bottom... as they danced, the bull sort of bobbed its head around. I asked a couple of people around me what it all meant, but neither spoke enough English to explain what was going on. The music was crazy and repetitive, and was phrased in such a way that I couldn't understand its structure until I'd heard it about a hundred times... seriously, these guys went for at least half an hour, until Eli and I finally took off to see an awesome mariachi band (and, of course, the lowriders).
