Do you have this rule at your track?

Wow. I have to ask: what track was THIS?

I think the closest we get to anything like that is "no offensive graphics or racer names."

Taking drag strip too literally XD

Definitely not a rule at the Canyon. In fact probably the opposite given all the bogan's hanging around. Certainly too hard to police it all :)

If Goat hill had this rule, no one would show up

and can't blame someone trying to make some$$$

Probably a bit of *wink wink* (nudge nudge) yaknowwhatimean.

As a young man, I worked as a tech for the school of oceanography at Oregon State University. Research cruises might last a week or a month at sea and among the research crew, there were often young college students who came along to help out. At the start of each cruise prior to disembarking the captain would come on over the ship's intercom and say the following:  blah blah about ships regulations and safety, and he would always end it with "there will be no fornicating or drinking on my ship."

I'm sure there was a little fornicating here and there, but I can certainly say there's a ton of empty vodka bottles on the sea bed between 40 to 100 miles off shore.

Nah, dude...that stuff is encouraged at my track! :D 

I typically don't go into the private lives of NITTRO SERIES drivers but last season it was easy to tell who tended to consult with their crew before the race and who consulted with Jack, Jim, Jose and Johnnie before the race. 

Could bring more crowds to the race event... more opportunities for the vendors! So long as it's censored.
