Lots of pictures of the parade left but I decided to look down the street for something different. Cinco de Mayo is a minor observance in Mexico (https://en.wikipedia.org/wiki/Cinco_de_Mayo). Here it is an excuse to consume large amounts of Corona beer and Jose Quervo tequila. As I have noted, St. Louis loves an opportunity to drink in public and this is a big one.
So the party spilled down Cherokee Street all afternoon and evening. Have a burrito with your booze. You could roughly translate chapparito as shorty, perhaps a reference to the owner.
