I wouldn't refer myself as a chemtrail or contrail expert, but on my weekend bike ride out to a lake 15 miles into the country I ran across this trail late in the morning that was rather interesting. http://s1333.photobucket.com/user/zentrait1/media/SAM_0171_zpsf97d04ef.mp4.html From a dark to a light trail.
The play on the name is not intentional, but I do see it, lol. I'm not really into chemtrails, but I thought this contrail was really bizarre. It actually starts ...or ends... at the horizon, and yet, not all of it is a white reflective contrail, it is broken mid stream.
