There is a reason why you see a bunch of people by the signs of national parks. It is the entrance to a place carved out and formed over an unfathomable time period. It is the gate to a wonder of nature that deserves respect, love and a feeling of accomplishment for passing the sign. When you cross the gate at a national park, you know you are in for a "wow" and a sense of wonder on how the place came to be. A national park gate is a Gate to Wonder.
