Long Description of Sighting Report

I realize the irony of today being April 1st but I will swear an oath that what I am saying is true and correct. The weather was so nice this morning that I decided to prop my front door open and have a smoke outside my office this morning. While enjoying my smoke and watching the clouds move rapidly North, I saw a contrail from what I at first thought to be an airplane. Looking closer I noticed something wasn't quite right so I grabbed my 10 x 50 binoculars to take a closer look. I observed the contrail moving rapidly and consistently from North to South but there was nothing that I could visibly see that was creating the trail The trail seemed to be appearing out of thin air, there was no aircraft. The event lasted only a few minutes. There were two separate cloud layers this morning and the event was occurring below the top layer.
