barricades and police tape. the stuff works pretty good.......and virus cops. it's the new norm.I wonder how that is going to work for tracks like Gainseville where you pretty much have to walk through a big section of pit area just to get to the stands? If the NHRA denies pit access there's going to be a lot of fans that will just say "screw it" and go next year. I know I would be one of them.
