Is that a UFO

During this trip we rarely drove at night. However last night we were determined to make it to south Dakota. The roads here are so dark and isolated we didn't know where we were. Rebecca kept seeing UFOs ahead. We passed many dead animals. Not sure what they were but some were missing heads. Yea.
We were also worried about forest fires. We finally found our budget friendly motel 6 and crashed! Mt Rushmore was next on the agenda.
