Well that's because you can count on one hand the number of actual serious researchers who can tolerate the reign of terror currently being waged by the Education Forum moderators! PS: agree that although these Clean Towel articles are well researched, there is not a shred of hard evidence to connect the truck to the assassination.
You got that "reign of terror" thing right, Tommy! When I departed - voluntarily asking my account to be deleted, I hasten to add - Kathy B. told me privately she was "sorry to see you leave" and that I'd be "welcome back anytime." These days, I'd be as welcome as a cockroach in a Happy Meal. Wacko Sandy Larsen has departed for Harvey & Lee Heaven (RIP Sandy, sincerely), but Mr. Niedernut belongs in a sanitarium and John Simkin has revealed himself to be w-a-y farther into the lunatic fringe than I ever imagined. All just IMHO, of course.
Royell is correct that the linen truck, as well as another large truck in the vicinity, disappear from photos pretty quickly after the JFKA.
