For residents of Boston and the marathoners who run through that city every spring, the Boston Marathon will never be the same.
The Boston Marathon is a celebration of the beginning of the revolutionary war, it's a holiday for state workers, and it marks the beginning of spring, a season of renewal.
Tuesday morning, though, on the day after, there was anything but a celebration.
National guardsmen were deployed underground Tuesday to protect Boston's subways, while above ground, police cordoned off a mile long strip of Boylston Street where the explosions occurred.
It's all one big crime scene, and could be closed for days.
Investigators now believe the two explosive devices were pressure cookers loaded with metal ball bearings designed to be more lethal than other devices.
Marathoners like Patand Corrine Gable of British Columbia, who between them have run nine Boston Marathons, say Tuesday's attack won't keep them from running more marathons.
"The last thing you want to do is bow to terrorists or people with an ill will," Pat says. "You certainly can't allow them to have that affect on you."
"This is something we need to move forward with," Corrine says. "Not let them win."
Friends or relatives of runners say they'd have no problem camping out at the finish line for future marathons.
"I'll be nervous," says Sheryl Gyr, the wife of a marathon runner. "I mean, I will be, but, it's just awful that such an amazing thing has to be marred by this."
All of the marathoners FOX 32's Larry Yellen talked with admitted that they're a pretty stubborn sort and that they won't back down in the face of adversity. I guess that's what you'd expect from someone who puts in the training and effort to run in such a race.
