People were packed tight in El Centro the night of the parade -super tight, like U.S.-football-stadium-when-the-game-is-over tight. And the paisas (people from Antioquia/Medellin area), and my group of ex-pats, were polite and noticeably not drunk (so completely unlike a U.S. football- stadium-when-the-game-is-over).
The paraders got right up in the faces of the watchers, shot water at us, and played all kinds of latin marching band music. The crowd went wild for all the action the parade brought.
