I heard back from the owner of Dupont Castle regarding a small group trip. I suggested a Saturday since some of us have longer drives and could use a day to rest afterward.
"I guess around noon would be good. I assume you would be here for about one to two hours. As far as I know right now, Sat the 16th or Sat the 23rd would be okay. You should keep weather in mind, one of the nice things about this place is the view from the roof, and if we have fog or rain, it kind of messes that up."
Let's coordinate something.
