It was indeed me! Good eye! Standing next to me is the lovely miss_amaranth, who you have now met. I'm not sure where cheshcat was at that point. Probably up on the nearby hill, getting a nice look at the Sun rising through the Stone arch... but also possible that she was already engaging in her tradition of making the rounds to give a greeting and a blessing to all of the Stones on the site.

P.S. Very glad that you were able to make it to the December PanThea NYC outing at last!
