Kinda funny, but deep staging is legal at any NHRA event, but it sure pisses off the competition. I know that at some of our local tracks it dosn't make sense, but you can deep stage only if you mark your windsheild with deep, otherwise they will disqualify you. I've never understood that rule,but i do know it's one of the easest ways to rattle your competition and i used to do it all the time when they allowed motorcycles to run in S/Pro.
