Myers renderings have the promise of being hugely helpful in interpreting witness testimony. For example, his view from Charles Brehm's perspective showed Brehm to be uncannily accurate in the details he described. His "then he went all the way down" statement is shown by Myers' model to be exactly what he saw looking at the retreating limo.

I've tended to throw my hands up and disregard all attempts to microanalyze DP witness testimony, but I think Dale's renderings open up the possibility of learning some new things.

:          His attempt to use the animation to demonstrate the Single

Martin is right about this, although I think this is easily within the margin of error of the model. Canning, for example, used the Croft photo to show that Kennedy's torso was slumped forward in DP, and Myers didn't seriously attempt to model the shape of Kennedy's back (which seems to me to vary a bit from the generic figures he used).

However, having someone like Martin around to point out stuff like this is the point of having people with different viewpoints.

:          A photograph showing FBI agent Robert Barrett at the Texas
: Theater, and a film clip showing him at the location of the shooting of
: Officer J.D. Tippit, made it clear that he was not the same man who was
: seen apparently picking up something from the grass in Dealey Plaza in a
: series of news photographs.
Agreed.

:            Controversial claims were challenged, a variety of evidence
: was presented and examined, and the participants had a stimulating and
: valuable experience. It was the kind of exchange that should happen more
: often, allowing vigorous testing of everyone's assumptions, a greater
: likelihood that untenable theories will be discarded, and a better
: chance to see where theories are the strongest. I hope it doesn't prove
: unique, as it's something we all could use.
Martin is being modest in not mentioning his slide collection, which is one fantastic resource. Largely due to Martin, I saw more photos relating to the assassination than I had ever seen before -- including numerous views not in TKOAP, not in POTP, and just flat-out not available elsewhere.

Martin unfortunately missed the session where we all shot the Todd's MC (he had some business in Grand Rapids). Although it wasn't any sort of "recreation" and didn't have any evidentiary value, it was a lot of good fun. We were shooting at a pumpkin at 20 yards. After a couple of shooters missed badly by relying on a misaligned scope, I actually got 2 (3?) hits using the iron sights. But then Jaynes and a fellow named Don (who had arranged for us to use the property) drilled the pumpkin right in the middle. Proved nothing, but great fun!

Steve Barber's hospitality deserves kudos. He made a weekend which was inherently going to be enjoyable into pure, unadultrated fun.
