Information on Chemtrails

www.raisethefist.com...

has a decent sized article on chemtrails. I live in Iowa, and have seen what appear to be chemtrails in the sky on several occaisions. I have very limited knowledge of aircraft, so I can't identify the crafts which appear to be spraying these chemtrails. I know of several people, myself included, who seem to develop cold-like symptoms or nausea shortly after these chemtrails appear. Maybe it's just allergies, maybe I'm paranoid. Any information would be greatly appreciated.
