One year after the terrorist attacks, it's the memories that cause her pain.
Hauser, a Manhattan resident, was in the subway beneath the World Trade Center towers when they collapsed Sept. 11, 2001. Eventually she emerged from the rubble, covered in dust, to find the building destroyed and her apartment uninhabitable.
She stayed in a New York hotel that night. Then, still covered in ashes, she drove 17 hours to family in Fort Lauderdale, Fla., the next day.
All of those thoughts came back Tuesday.
"When I came out (to the site today), it was kind of a frenzy," Hauser said. "It's very anxiety-provoking. I see it, and I can't breathe."
Battery Park City was made from the dirt displaced when construction of the World Trade Center began in the late 1960s. Before Sept. 11, people came to the park to walk dogs, jog, bike and catch a glimpse of the sun setting behind the Statue of Liberty.
The dogs and joggers remain, but now many of the park's visitors flooding the area focus on a memorial, which contains objects from visitors and family members of people who died in the attacks.
Decorating the site are hundreds of patches donated by police officers, firefighters and service personnel from San Francisco to Winston-Salem that form a banner across the memorial's top. Other gifts include a singed firefighter's jacket with the words "best friend" and a stuffed Smokey the Bear holding a U.S. flag.
Eleanor Lang, a Manhattan resident who visited the memorial Tuesday, said everyone -- even her dog -- has been acting strange in the past week.
