I took 3 exposure, and this was my last.... just before a ranger with a very bright flashlight yelled at me to get down from the arch (30 foot climb to the top) and almost gave me a citation. Was it worth it? Yes! Although I didn't see any signs in the dark, I explained to the ranger that I had no intentions of disrespect and then showed him the picture. One look at the back of my camera and he told me that it was the best picture he had ever seen of his beloved arch, and to be careful in the dark hiking around with my camera. We left on good terms, but I won't be climbing back up there again. I just ordered a 30 x 40 canvas enlargement of this picture and WOW... it really pops.
