Actor Tom Selleck, known for his work in the TV show "Magnum, P.I." during the 1980s, is the project's new spokesman. He served in the California National Guard during the Vietnam era. His friend Ron Montapert went to Vietnam but did not come home.

"Across the street from here is a wall with more than 58,000 names of those who made the ultimate sacrifice for their country during the Vietnam War," Selleck told the 100 or so people attending the ceremony.

He said the Vietnam War taught the American people to separate how they feel about the troops from how they feel about the war

"That black granite wall taught us a lesson as well," he added, "that we must never forget those who fell." Selleck said the new center "will take us from thinking about the 58,000 as a group to thinking of them as individuals."

"I would like to say to all those who served and sacrificed in Vietnam and in all of America's wars, thank you for your service and welcome home," he concluded.

Scruggs noted that both The Wall and the replica honor the courage, sacrifice and devotion to duty and country of the people who answered the call during America's longest war. He said the memorial brought long overdue recognition and healing for the participants and family members and became a symbol of reconciliation and healing.

But, he noted, The Wall That Heals has become the memorial that educates people across the country. The traveling wall and new exhibit, which includes teddy bears, photographs, letters, baseballs, a motorcycle, combat boots, flags, and medals, soon will be on tour in towns and cities throughout America.

Exhibit designer Paul Appelbaum said some of the letters in the exhibit were written at the wall "out of sheer impulse," while "others have been carefully crafted and left in a very precise way."

Appelbaum read one letter as an example.

"'Dear Dad, I'm sorry it took so long but when you went away I was 8 years old and I couldn't understand why you never came back to us. I'm now 35 and I can understand now as I have fought in two wars myself. It's not much fun, it it? You might like to know that you have three grandchildren, two girls and a boy, and they all know about you. It meant a lot to me to see your name on The Wall with all the others. Your loving son, Paul.'"

The objects left at The Wall "illustrate loss and grieving, Appelbaum said, "but they also celebrate a bond of love and friendship and even happy memories."

"They represent a treasure trove of conversations about the deaths of sons and the births of granddaughters," he said. "That's what this center is dedicated to and that's what you'll see as you stroll around the portable wall as it begins its journey around the country."

As founder and president of the nonprofit Vietnam Veterans Memorial Fund, Scruggs raised nearly $9 million to build The Wall through private contributions from corporations, foundations, unions, veterans and citizens groups, and more than 275,000 individual Americans.

Scruggs now intends to raise up to $100 million to build the underground museum to exhibit the photographs of the men and women whose names are etched on the black granite wall. He also plans to display some of the 100,000 mementos visitors have left at The Wall.

"Remember that what we're doing here is remembering values," Scruggs said, "the values of our active-duty servicemembers today, the values of loyalty, respect, duty, integrity, courage and service.

"These were shown by the fellows and women who served in Vietnam, by the people who are serving today, and by the people at a place called Lexington Green in 1775 who stood up against the British to get the American people our freedom," he said.

So far, the memorial fund has raised $18 million for the project, including $10 million from Time Warner. Today, Rolling Thunder donated $25,000 and Iraq and Afghanistan Veterans of America donated $5,000. Representatives of the three organizations attended the ceremony.

Lisa Quiroz, senior vice president of corporate responsibility for Time Warner, said the first time she visited the Vietnam Memorial she was moved by the fact that the memorial recognized "the feats of ordinary citizens -- our brothers, our fathers, our sisters, your children."

"At the end of the day, our democracy is what it is because we have young people that sacrifice for this country and our democratic ideals," she said.

Quiroz said that when Scruggs introduced Time Warner to the concept of the education center, the corporate officials realized that the letters, photos and teddy bears "represented years of experiences that had been missed by the people that were memorialized on the wall."

Of all the requests for support, she said, Time Warner executives thought the education center provided a unique opportunity "to give every visitor who came away from The Wall a profound sense of gratitude, and a deeper understanding of the meaning of patriotism."

Todd Bowers, director of government affairs for the Iraq and Afghanistan Veterans of America, thanked the Vietnam veterans for their support of today's troops.

"We're the new, young generation of veterans," Bowers said, "and if it wasn't for all the support that we've received from veterans of previous conflicts, we would be having a lot harder time right now. I thank everyone from the previous conflicts for looking out for us and making sure that those guys over there are going to be taken care of before, during, and most important, after war."

Artie Muller, Vietnam veteran and chairman of Rolling Thunder, said, "Welcome home to all the veterans who are here. And to those who gave their lives, we'll never forget them.

"This is a different war, a lot of women are in this war, and it's altogether different than during the Vietnam days," Muller said, addressing the troops now serving in Iraq and Afghanistan. "We know you guys and gals are doing a great job and we're real proud of you. Us Vietnam veterans never want to let what happened to us, happen to you."
