This is one of the biggest holiday weekends of the year, as celebrations of Mardi Gras, Valentine's Day and Presidents' Day overlap and blur. (Sadly, no one organized our dream soiree with a brass band performing for singles dressed as Babe-raham Lincoln and other sexy presidents.) We have separate lists for the area's best Mardi Gras parties, Black History Month events, Lunar New Year celebrations, and Valentine's Day activities for singles and couples. While some events from those roundups are featured in this week's column, not all of them are, so we encourage you to check those other stories.
