Chemtrails?
I don't know about the whole chemtrail thing, and I don't know what these are, but I'm sure they are too low to be regular jet contrails. They also stayed in the sky for about an hour, before disappating into what looked like a think cloud layer. I took these from my house on 10-19-2004.
If anyone has any factual evidence/explaination on what this is about, I'd be very interested to know.
