Super long restroom line for the women's and not the men's?

So, I was out at our 4 day county fair over the weekend. Crowds of people all over. When I went over to use their restrooms, I noticed how very long the line out the door to use the women’s was. I’m a male so it didn’t bother me. Ours had a short line, but it wasn’t bad and it moved fairly quick. I was in and out in not that long. The woman’s was still just as bad and backed up when I left. I just have to wonder why the women’s takes so long to use? Never thought about it much til now, but it was like that both days I went to our fair.
