March is the month that finally admits winter is losing. Spring shows up on the 20th or 21st, Women's History Month runs the full 31 days, and St. Patrick's Day turns entire city blocks green for a Tuesday afternoon. It's also the start of the NCAA basketball tournament, the real US sporting holiday nobody put on the calendar but everyone treats like they did.
