'Comely maidens dancing at the crossroads' was what started it. DeValera's dismissive comment regarding women's roles in his vision of a new Ireland. Misquoted, of course, the actual word he used was 'happy'. So there we were, a bunch of women activists with nothing to do on Mayday (No RTS, aaaahhh) but be happy.
What better place than at the crossroads beside Herbert Park and the US embassy, right in front of DeValera's monument. Throw in a bit of dancing, a picnic with free food for all, send out a few invites, and see what happens...
