Let me start by saying I am a NASCAR fan and (obviously) a Vegas nut too, so coming to Vegas for a race last year was a big treat.
I was talking to a lot of the dealers, bartenders, servers etc. and they all agreed that NASCAR fans are some of the best in sports. The waitress at Ballys said they tipped well and were polite. She mentioned the NBA All star weekend was awful and that for the first time ever, they had to shut the restaurant down during peak breakfast business because of the fights. She also said the MMA/UFC Crowd seem to be angry and aggressive all the time.
A bartender at GG told a great story about race 2 fans arguing over drivers, and they almost started fighting, but no punches thrown. He said later that night, the same 2 guys were back at the bar, laughing and drinking together.
Say what you will about race fans, but they/we are a loyal bunch..
