John, in the Nix film beginning at the steps. 4 oaks trees, 1st is in shadows just left of steps, 2nd is almost parallel with Fort Worth sign, 3rd, and the 4th is about 15 feet from where the wood fence merges with the concrete embankment. All of their trunks show up dark, the 4th tree, about 5 feet up from the ground is a light colored plume. It dissects the trunk which appears to be about 10 to 12 inches in diameter. There are no forks in the trunk for another 5 or 6 feet up so there is no way it is light shining through. If that is a smoke plume drifting out from the fence about 15 feet away then it matches Mr Dodd, Mr Price's statements. Since its a right angle view its hard to determine how close it is to that 4th tree. One things for sure its between that dark trunk and Nix's lense. It is probably what Mr Holland referred to as well but he put it further down to the east. Mr Dodd and more especially Mr Price were at more a right angle to the fence then Mr Holland. Its easier to pinpoint the origin of something coming more direct at you then you viewing it moving perpendicular to your position. Its less visible in the Bell film but its there as well. It shows up in the Nix film as the limo evens up with the Fort Worth sign so its captured sooner. Please view and let me know if you see it.
