I went to the Cardiff meeting on my own, and I'm so very glad I made the effort.
There were difficulties (no protesters that I saw, but the original venue cancelled at short notice, necessitating another venue at short notice, and wonderful people with cars ferrying people from the first venue to the second! And lots of spontaneous conversations among strangers during those car ferryings, around, "WTF?! In 2018?! Pressure is put on venues to prevent them from hosting women talking about women's rights??!! WTF???!!!!")
There was such an atmosphere of solidarity about women's rights, and the speakers were inspiring! A very invigorating evening.
