I used to race motocross with three 6's on the bike, never had any trouble.
(Bikes have a front and two side number plates for those who are wondering.) Now the overall immature behavour of the bike itself was another issue, though.
(I had finished sixth overall out of forty riders in the +25 Beginner class the previous year.)
I do know a few other "sixers" who would put a fourth six under the rear fender to "break the curse."
I too would rather think of this day in Honor of those who sacrificed all on D-Day. Big salute to them!!
