Number 3
Speaking of superfans, this guy right here is one. Unless he just likes the number three and likes to pull off his shirt while watching races which is very unlikely. Or perhaps he has someone in the Number 3 car that he’s rooting for. Whichever way it is, this probably counts as one of those extreme shows of solidarity.
Moving away from the number 3, can we talk about his body hair? The ultimate NASCAR fan, he’s put it into good use while some other people would probably shave it all off.
