It was women gathering to remind the people in charge that they vote, and they will not tolerate losing the rights that women have been fighting for over the past century. Donald Trump is just the most high profile threat to those rights.
The original plan for today was for me to take my 4 year old daughter to ballet while my wife went to the march. My kid asked what a march was, and my wife compared it to the scene in Mary Poppins when they march for women's suffrage. After that, she wanted in, and she had a great time. I'm proud of both of my fierce girls.
