I shall try this again, with links this time.
I have obtained an Aerial photo taken of Airdrie and area including the DG Acreage in it. I can zoom into it quite well. It was taken on July 1st 2014. I have compared this photo to one of the photos that was taken during the CPS and other agencies searches on July4th/5th. This photo has been shared around on the net quite often.
In the July 1st photo. You can see by the burn barrel location there does not appear to be the woodchipper here. But up behind Outbuilding #3, it appears to be there.
In the next photo taken by LE... no woodchipper to be found behind Outbuilding #3, but appears to be back at the burn barrel location.. Also in this photo the lawn is noticeably different, looks freshly cut.
Also the blue speck on the left hand image zoomed in, appears to be a person based on the shape/size of the shadow.
Photo 1 (July 1 2014) & close up of blue speck obtained from here:
