Tone3,
I'm not trying to change your mind but here are a few items about chemtrails.
This video/radio interview with an ex-government employee speaks up about ongoing program to spray.

I know the difference between contrails and chemtrails. They are very different. About 6 years ago a friend tried to tell me about chemtrails and I was exactly like you, bah humbug, they don't exist. After a lot of research on my part and looking up at the sky every day I had to call him and tell him that he was right. I'm not saying that they are for a bad purpose, although I believe they are, but make up your own mind but do some research on it. It might surprise you.
I don't mine being your 666 post. I'm not afraid of a number.
