Today about noon on the way to Mass the sky was clear except for the massive chem trails all over.

I think it is light metals like aluminum.  

I've been noticing the sky over the past several months.  It seems that, at least, in the skies over Central Indiana, the chemtrails have completely disappeared.

The only thing I've seen all year following high flying jets is the ordinary contrails of vapor that dissipate fairly rapidly.  On very humid days the contrails may stay around longer, but they don't slowly spread over the entire sky like they used to--that is, when it was apparent they were spraying something in the air.

Has anyone else noticed an absence of chemtrails this year?  Or is it just Indianapolis that is being spared?

Not at all!  Here in Southern California, the almost daily heavy chemtrailing is business as usual.

The aluminium in the chemical trails functions as a slow-acting defoliant, or so I've read. I've no reason to doubt it, though I would have to research the matter a bit to be sure. It would certainly fit with the programme of depriving the goyim/proles of any means of resistance. The control of food has always been used by tyrants to control their slaves. The food itself has nearly all of it been poisoned. GMO's, monosodium glutamate, high fructose corn syrup, TBHQ, aspartame & who knows what else is added to the greater part of what is sold in supermarkets today. Unpoisoned food is rather hard to find, but well worth the effort & extra money to avoid the consequences that come with ingesting the vile poisoned slop such as McDonald's &c. Getting back to the chemical trails, another interesting function is that they can be used to make more efficient the functioning, or intensify the effects of electro-magnetic weaponry such as the old Soviet "woodpecker" as it was called, or the somewhat more modern HAARP array. (somewhat more modern, as we have no idea what they've really got in this day & age, new technology is only released to the proles if it will somehow assist in their enslavement, such as the computer, which has made feasible for the first time in history the continual surveillance of just about everyone on earth) A good place to start is with the research conducted by Dr. Clifford Carnicom. Just type in his name, it ought to come up near the top. I would include a link, but I'm not so good with computers. An added benefit from their point of view, is that it causes pulmonary difficulties, especially in the elderly & those already debilitated by disease or injury of some sort, & hence assists in the de-population programme, along with bringing in greater profits from the sales of medicines & various forms of treatment for those whom it does kill outright.
