On race days, the entire concourse at Charlotte Motor Speedway is teeming with race fans, and so, in the best of times it is a tough security assignment.
After last week's Boston bombings, the speedway said fans should expect even more security and maybe longer lines to get inside.
Long before the stands fill up with race fans, new security plans are being discussed in the aftermath of Boston's Marathon bombings.
It took speedway president Marcus Smith almost no time to act.
"We have already had those conversations very quickly. The next day after the Boston tragedy and we have made some plans," said Smith.
What those plans are is something neither Smith nor FBI, ATF, Homeland Security or local police agencies he is meeting with want to discuss publically. However, he said not only will fans likely see more security during race week. They will also benefit from undercover efforts too.
The speedway has some security assets and surveillance assets that nobody ever sees.
Last weekend at the zMax Dragway, the speedway said it began implementing security changes for fans and track workers.
For the Coca-Cola 600, the stakes are much higher, for the speedway and fans.
"I do not think anyone should be afraid to come to those events, but the security needs to be stepped up," said race fan Frieda Strub.
That could come at a cost for fans, but it is one Jonathan Cerdan said he is willing to pay.
"This is such a large event I would no issue with any added security if it made it slower to get in. As long as everything is safe," said race fan Cerdan.
There is no question that the events in Boston last week have gotten the speedways attention.
Marcus Smith and Concord Police said the security plan for race week is still evolving.
