It is the beginning of the rut at Yellowstone, and the bull elk are coming around to check out the females. The sounds of the bugling bulls wake us up at night, and we have to look around as we walk outside, because the bull elk are dangerous and unpredictable. Yesterday, two beautiful males with huge antlers appeared on the lawn and proceeded to circle each other and the tree between them, before engaging in some clashing of antlers. The fight didn’t last more than fifteen minutes or so, but the tourists gathered, getting ever closer until the rangers appeared to make them back up. I was in the relative safety of the front porch, but ready to run inside if they got closer.
