My son was running half midgets in QMA and was bugging me for a yellow tint shield for running at night. Well he got it and.the first night he was leading the feature by almost a half a lap. Well he took the white flag and backed off and got passed going down the back stretch and and then took off coming out of 3 to finish second. I asked him what happened thinking hit hit the kill switch or something,nope he said he thought the yellow came out forgetting about the yellow shield which made it look yellow. We still laugh about today although we didn't that night...lesson learned.
