Streak in the sky

We are not sure what the white streak is in the top left corner of this picture. Thought it looked interesting enough to show. This picture was taken at the very beginning of the day when we first got there.
Mist

This picture was taken on the burial ground at approximately 9:30pm. There were 3 of us out there. Jason took this picture while holding the camera at arms length. The other 2 investigators were a few feet away behind him. We believe that this is not a breath and know that it is not cigarette smoke.
