The Chapel of the Sacred Heart is located in Grand Teton National Park and is open to the public. While I was inside taking pictures of the church, a woman was there vacuuming the carpets. She asked me if I would prefer to have the lights on. Of course, the interior of the chapel looks much better when it's lit. Once I captured a series of photos, she turned off the lights and left. Since the light switch is not accessible (she had a key to the door for the light switch), I was lucky to be in the church during that short window of time when it was being cleaned!
