Thanks for posting this overhead view of Dealey Plaza. I realize this is probably a pic taken the following day, but that is a very Large Stain inside the Parking Lot. That Large Stain is close to the very (N) end of the N-S section of the picket fence. Very close to the section of picket fence that the guy/kid is peering over on Towner 3. Whatever caused this Large Stain, could be what attracted that guy/kid's attention and enticed him to climb atop the picket fence. Also, per Skinny Holland during his Mark Lane walk-through, that parking lot was Jammed with cars on 11/22/63. There woulda been a vehicle parked/positioned where we now see that Large Stain.
Also, how could anyone on the tup be looking near the manhole in question when jfk was way way left in their field of view?!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Unless of course the proposition is that the shot(s) that hit grass/manhole were at near say Z400, ie when jfk was near the manhole.
The stain haztabe water, ie where there had been a rain puddle in the graveled carpark.
Judging by the shadows the pix was late arvo.
And the carpark would be near empty on Saturdays i think, or at least on Saturday arvos.
The fact that there are any cars at all must be due to the shooting on the Friday.
See the 2 big cabinets, near the splay, near lots of gawkers during the shots, & one of thems cabinets is where Hoffman says a tossee dissassembled a rifle, ie in full view of say 15 gawkers, including 2 cops.
