a "fast group of Harley guys"? puh -LEEZE! more like, some dofus in a hurry wanteing to get past the van - or whatever the folks with the video camera were riding in - and the macho retard on the lead bike burns past, and then chickens out about leaning it over far enough to make the turn back into the lane in front of the camera vehicle.
they probably all blamed it on the "cage"
the guy in teh camera vehicle put it best:
"***** idiot".
