... Certainly no Tuscan sun. Im just east of Tuscany and regarding the sky, why things seem no different then the good ol' U S of A. Its raining here actually, and for the past two days they blotted out the sun with heavy aerosoling. If you looked hard enough, every once and awhile when there was a parting in the sky, you could spot those phoney wisps higher up in the atmosphere. Ive come to suspect they fly near almost everyday, even those cloudless days. If you discern your local flyboy patterns and just watch the sky you'll see them flying even if they arent letting loose trails, I just call it the "Good Stuff" when theres no visible aerosol trail.
PS- They're sure lazy here, they even layed down some turn around trails, something I hardly have seen.
