I live east of Bangor and have been watching the spraying activity daily. Here's what I've seen.

Spraying became very heavy in 2008 with large plumes all over the sky daily. In spring 2009, suddenly, the large plumes decreased in frequency from daily to about once every week or two. Now, I daily see short plumes being spraying by low-flying jets at a rate that is often as frequent as one jet every 2 minutes. It's not uncommon to see jets in formation of 2 or 4 jets. Here's a picture I took:

Since I can taste the air when they spray, I can tell you that the persistent plumes taste like salty-metal. These non-persistent plumes have a taste similar to a sleeping pill or asprin. This type also burns my sinuses horribly and causes a lot of physical symptoms that are identical to mercury poisoning.

The spraying for the past week has been on a very regular schedule. It gets really heavy about 3am and continues until about 7am. I am judging these times by when the taste in the air is first detectable. It takes about 15 to 30 minutes for the taste to be detectable after it's sprayed.

I am now having heart problems and chronic headaches (and a bunch of other symptoms) because the spraying is almost constant but normally not visible unless you watch the skies for the short, non-persistent trails. When the spraying stops (the air has no taste to it), all of my symptoms disappear in about 60 minutes. I feel fantastic at those times.

I certainly hope we can find a way to stop this.
