Chemtrail: What in the World Are They Spraying?

I love all the "scientist" on the street giving their highly "educated" opinions.

I suspect they are spraying dihydromonoxide in microscopic solid form

Oh no now this is getting too much seeing this posted after hearing it on that late night talk show that features people who have been taken aboard a space ship and the fellow trucker who saw the space ship over Atlanta Ga one night. What in the hell is next for some idiot to post on this site????? Why dont they go to the UFO site and post there there is nothing being sprayed that just water vapor from the jets. What sometimes happens is the black water tank in the AC will leak forming a brown trout ice cube which when the AC comes to a lower warmer level will fall off making a smelly substance nothing more nothing less.

So should I ignore all the parallel lines across my city and what we already know about cloud seeding? My concern is that the real pros who are actually investigating this stuff might be right about additives such as barium and aluminum... Denying the parallel lingering lines in the sky is like that of the ostrich, head in the sand and whatnot. The only thing I hear from people who compare me to the idiot in their heads is "I need to feel better about myself by guffawing at an internet stranger" and "I have no real opinion because I am unable to think for myself".
