All law enforcement is already on high alert. And because there have been so many warnings, citizens really aren't sure what to think.
"They have issued a number of those so I don't know whether to be concerned or not," a citizen says.
"Almost like they're not as important as if they were issued less often," Nick Liberty says.
A local professor says those are common reactions, "All of us can only handle so much anxiety and stress and at a certain point we just say this is enough I just can't worry about it anymore," Ron Kraybill says.
This warning was based on an audio tape believed to be from bin Laden, also last night's execution, in Virginia, of a Pakistani man and finally an FBI bulletin warning of a strike with mass casualties.
"I'd say this area makes me less worried, because I don't see Harrisonburg, Virginia as a threat," Liberty says.
"There's a lot of America out there, I'm not concerned," Cayce Powell says.
"Still terrorists want to look at where they can hit where you think you would never be hit before so therefore that puts the hair up on the back of my neck as to where we're weakest," Sheriff Don Farley says.
Which could be Interstate 81.
"It's a direct threat from North to South on the eastern side of our country," Sheriff Farley says.
But, Kraybill says there's more to fighting terrorism than security.
"We need to get beyond just throwing up more bars up on the doors-we need to start asking why are these people attacking us," Kraybill says.
He says be diligent, work together to notice danger, and recognize there are limits to security, finally, that risk is a reality.
"Everytime I get in my car I know there's danger, so I don't need to be reminded constantly it's dangerous, however if there's a collision straight ahead of me I do want to know that," Kraybill says.
The White House is leaving the national alert status at "yellow.” That's because the threat's not specific.
