How was your experience?
The weather was hot and the tour guide was sensitive to it and kept us in the shade the best he could. I've lived in this area all my life and have never closely observed the gargoyles on the Cathedral and everyone in my group was pleasantly surprised by how funny and imaginative they were. There's even a Darth Vader grotesque up there. It was fun and the group consisted of all locals which was nice. We forgot our binoculars and the tour guide had a pair for us to share but definitely bring a pair with you. I consider it a must for any D.C. native.
