Retraction of one aspect of the "great event" post

I could let it ride and I doubt anyone would uncover the obvious but subtle contradiction between two of my posts.

My third trip to Green-Wood Cemetery in the mid fall was, among other things, purposed to determine if the "Great Tree" obscured the view of Lower Manhattan.  As I determined, I could see 1 WTC from Mr. Gann's grave and my line of sight was a few feet (maybe 5 or 6) right of the tree and elevated.  On that third trip, the view was just a bit hazy, but we all three (myself, daughter and son-in-law) could see the unmistakeable tallest building, 1 WTC, through the limbs of the great tree on its right side.

In my immediately previous post, I use cellular GPS coordinates of gravestone #3 (WD Gann's) and cellular GPS coordinates of the trunk of the "Great Tree" to draw a vector that intersects the otherwise very notable intersection of Lafayette and Worth streets.

The two observations are geometrically impossible.  If the GPS coordinates I took figured Lafayette and Worth through the Great Tree, the line of sight of 1 WTC would have to have been to the left of the Great Tree.

Something's simply wrong and I'd consider the error as placing cellular GPS locations on Google Earth satellite GPS measurements.  [It may be that the cellular GPS coordinates are correct relative to each other and, using the distances they compute between stones, might validate the same measurements derived via Google Earth measurements.]

Despite this retraction, there remain curiosities associated with the intersection of Lafayette and Worth and Federal Plaza and the date, October 19, 2016, but the above is a setback.
