These are the coordinates that I have for the Hicks placard find. I believe I got these from Bruce:
46°14’38.4″N 122°41’01.3″W
Correct me if I am wrong, but I believe that puts it to the west of the both the FBI flight path and the centerline of V23.
Another thing that we cannot calculate for are things like updrafts, downdrafts, rain, etc. Not to mention any mechanisms on the ground that could have affected it's final location such as wind, water, animals, human intervention, etc.
