Well darnit! I was moving around all the time too! I guess we missed each other! Hopefully I will have ya in one of my pics. :) I figured out who Libertina was. Do you know anyone else that went?
LibreOuMort (who is very quiet on this site) was there. She was on the northeast side of the overpass, a short heavyset woman in a navy coat, waving a flag with an eagle at the top of the pole.
My photos had only one woman in a red sweatshirt, but she was waving a sign and the little girl who held the flag in her mouth while she warmed up her hands was with her.
