More great work! Yes, get the high res to see the car and who might be with him. I bet it'll still be hard to tell. But maybe.
I think Frank needs a "CheatLinks" (instead of Athlinks) page. Can someone organize a list of his races, with links to the pages with evidence of how he cheated in each one. All this great work is getting buried into the pit of of this thread.
Also, for those with the sleuthing skills and lots of time, is any chance of finding similar pics of Frank off course for Phoenix 2019? I think that DQ matters the most, since now it stands as the fastest recorded marathon for 70+.
