The story does end well - he was not injured (just a scrape on his arm) and was able to get back in his kart the next day and race to 2nd overall in his class. He’s getting quicker and quicker every race and is learning his race craft quickly. Here’s a lap from one of the Heats on Sunday at @UtahMotorsportsCampus. #kartingkid」9月11日 7時31分
