There is one of the largest chemtrail dumps I've seen going on over Toronto, Canada now - 1:30pm, April 6, 2013.
Think blue skies and send thoughts of blessings to those doing this crime - as what you send out, you get back. But, know that they are accountable for their crimes and what they are putting out will come back to them many times over.
Don't fall into the trap of generating hate and fear (and other negative emotions) in yourself, and projecting that feeling out into the world, as you will get that back. Stay positive!
Hold the intention for a blue, clear sky, a world of peace, and keep spreading the word about chemtrails and about what thoughts and feelings you give out come back to you, many times over!
