Denver130:
Sorry to hear about your health problems.
The health issues you and some of your neighbors have been experiencing are not necessarily 1) caused by airborne chemicals and 2) statistically abnormal when compared with other communitities across the nation. Remember, in order to make this case, you've got to show that these suspicious atmoshpheric phenomenon cause (or are highly correlated with) health problems. Today, this would be a practically impossible task. Why? You'd have to collect data on chemtrail frequency nationwide. Unfortunately, there's no nationwide, standardized, scientific method for doing that at the moment.
As to the existence of chemtrails, here are a few thoughts:
1) If there exist documented cases of "contrails" existing where themodynamics does not predict their formation, then logically either it isn't a "contrail" or thermodynamics needs some tweaking.
2) If we assume that themodynamic theory is always correct in predicting contrail development, and these documented cases of abnormal "contrails" do exist, then these are not contrails. Then what are they? The only way we'll know for sure is to collect samples from these abnormal contrails and compare them against samples from normal contrails.
Can you show us some evidence of contrails existing where thermodynamics does not predict their formation? You'll need to show precise atmospheric conditions at the "contrail", then an official set of criteria for the development of contrails.
If it does turn out to be some sort of spraying sponsored by the military, I wouldn't be too surprised. The sheer volume of information the public doesn't know (or want to know) regarding certain elements of the gov't is beyond measure: JFK, TWA 800, UFOs, etc.
Anyway, in order for this chemtrail business to emerge from the fringes of conspiracy theories, precise, verifiable evidence must be collected and made public.
