The problem with writing a May events column (insofar that writing about parties for a living is a “problem”) is that it’s very tempting to just list 20 Cinco de Mayo parties. They all sound great and I’m jealous of everyone who gets to go to all of them. But, in a feat of remarkable restraint, I only wrote about two of them, and one of them is the legendary BostInno de Mayo. With the first weekend of the month featuring Cinco, the Kentucky Derby, and opening day of the SoWa Open Market, be sure to save some energy for the rest of the month.
