Quite a long article about chemtrail folk:
Patrick Roddie films the sky every day. Two years ago, he rigged a camera on the roof of his apartment building in Lower Pacific Heights to record timelapses of the sun's dawn-to-dusk arc, along with the sky's usual bland traffic of birds, airplanes, and clouds.
Many of Roddie's timelapses — which he uploads to YouTube — capture something else, too: hazy, white threads that thicken in the wake of airplanes and sometimes tattoo the sky in grids. To the uninitiated, these are contrails, the harmless water vapor that commercial planes spume as they track across the sky at 30,000 feet. To Roddie and his followers, however, these are chemtrails, the toxic signature of a covert government program to slow global warming and control the weather.
Roddie knows this sounds like boilerplate conspiracy theory. "Don't trust me," he says. "Assume I'm full of crap. I'm just some Irish guy."
