Some were too young to remember. Others recalled the moments the fatal shots rang out as President John F. Kennedy rode through downtown Dallas in a motorcade 25 years ago Tuesday.

The city planned no official ceremony to mark the passing of a quarter century since Kennedy's assassination, but on Monday hundreds flocked to Dealey Plaza, where he was mortally wounded at 12:30 p.m. on Nov. 22, 1963.Other organizations planned remembrances Tuesday at Parkland Memorial Hospital, where Kennedy was taken after being shot, and the Texas Theater, where Lee Harvey Oswald was arrested hours after the assassination.

On Monday, the focus was the memorial that marks the tragic location: a stone slab inscribed with Kennedy's name and surrounded by partial walls.

Ernest Saucedo, 20, of Dallas, hadn't been born when Kennedy died, but he visited the memorial anyway.

"I just made it my business to come by," Saucedo said. "I just feel I needed to come by. This is history."

Raul Miranda, 40, was in Dallas for a convention when he remembered the anniversary and decided to visit the memorial before returning to Los Angeles.

It's something that I can tell my kids what happened," he said. "I'm going to tell them that 25 years ago this event changed the history of the United States, the history of the world."

At Parkland, five doctors and nurses who were at the hospital when the president arrived were to participate in a roundtable discussion Tuesday.

At the Texas Theater, Dallas-area artists, poets and musicians planned a series of exhibits and live performances.

On Sunday, 30 former Green Berets and 150 onlookers gathered at the Dealey Plaza memorial to remember Kennedy. The members of the U.S. Army Special Forces wore their berets _ authorized by Kennedy in 1961 _ as they saluted four wreaths at the memorial.

In front of a plaque at the plaza lay a small American flag with a bouquet of flowers, about 200 yards from the memorial and across the street from the Texas School Book Depository Building. Authorities say Oswald opened fire from a sixth-floor window there into Kennedy's motorcade.

The attention given the 25th anniversary has roused more interest than usual in the site, said Gary Mead, who drove a tour bus that stopped at the memorial Monday.

Dallas native Darrell Jordan, making his first visit to Dealey Plaza, spent about an hour Monday touring the area.

"I've been watching all of the (television) specials the past several months and trying to formalize my own opinions" about what happened, he said. "I've been walking all over the place."

Jordan said he was disappointed the city and county planned no formal anniversary ceremonies but said he thought he understood why.

"They (local officials) worked 25 years to try to get the nation to forget it," he said.
