Hi Ken,

A few months back, it was thought that these contrails weren't normal looking and that some kind of web was being created. I think the thinking was that some kind of chemical, or whatever else you want to call it, was mixed in with these contrails and causing deaths in these locations.

As far as I'm concerned, the jury is still out.

San Luis, Colorado? Its been a couple of years since I've been thru there. Ever hear of Wild Horse Mesa?
