Maybe they were spraying aphrodisiacs for the "bigfoot" so they would multiply?
BTW, most airliners are white on the belly.
When you see a large number of contrails seeming to converge in one area, you most likely are near a VOR station, one of the radio navigation aids that aircraft use in navigating accross the country. They fly from one VOR station to the next, hence many pass over the same area.
A sprayed mist would be very unlikely to leave a lasting white trail in the sky.
As eagl noted, you saw contrail development.
