When I realized that my return drive would take me past Zion, I decided to add another day to my trip. I camped at the Watchman campground (hence the title). Of course, I couldn't help but try to take advantage of the lack of light pollution. I've yet to make a serious attempt at star trail photography. I basically took a couple of 30-minute exposures and called it a night (it was cold). One day, I'll figure this out and do it properly.
