One of the most interesting events was a fine view of the 22 degree halo and the circumzenithal arc at the Stellafane Convention in Springfield, Vermont. No one else was nearby and although it lasted at least 15 minutes, I never ran into anyone else who saw it that day (I do have a photo of it by the way).
I've fallen far behind in posting photos in this thread but here's a shot that I took at Stellafane on August 10th.
