Simi Valley, Calif. ? Nancy Reagan touched her cheek to the flag-covered casket, then made way for Americans by the thousands to pay respects Monday to Ronald Reagan before a cross-country journey to a state funeral in Washington.

A steady, near-silent stream of people — some saluting, some praying — circled through the rotunda of the Ronald Reagan Presidential Library, where the body of the nation’s 40th president will lie in repose through today before traveling to Washington. After Friday’s state funeral, the body will return to California for a hilltop burial service at sunset.

A Marine Corps band played “Hail to the Chief” as eight armed forces members carried the casket into the presidential library, past a 10-foot-tall sculpture titled “After the Ride” depicting Reagan as a smiling cowboy with a Stetson in his hand.

The journey began at a Santa Monica funeral home, where the mahogany casket was placed aboard a hearse for a 40-mile drive to the library in Simi Valley.

Clusters of people watched from overpasses and roadsides as the motorcade headed north, then west on the Ronald Reagan Freeway, its path cleared by motorcycle officers. One banner hung along the route declared, “God bless you Ronald & Nancy.” Another proclaimed, “God bless the Gipper.”

Flags at half-staff fluttered under an overcast sky as the casket was carried into the library rotunda before a brief family service.

“As we were in procession, I couldn’t help but think of the love and the outpouring that has begun in the nation for a great president, a great world leader and a faithful servant of almighty God,” said the Rev. Michael Wenning, retired senior pastor at Bel Air Presbyterian Church, where Reagan had worshipped.

When the service ended, Nancy Reagan, dressed in a black suit and pearls, walked to the casket, placing her left cheek against the flag’s field of stars. Her daughter, Patti Davis, hugged her tightly and other family members joined them, placing hands on the casket.

Soon after the family departed, the first of many chartered buses arrived, bringing members of the public who had been waiting — in some cases for hours — for a chance to pay respects to Reagan, who died on Saturday after a 10-year struggle with Alzheimer’s disease.

Michael Wenning, before the public viewing period began at the Ronald Reagan Presidential Library in Simi Valley, Calif. A state funeral is planned for Friday.

Between noon and 5 p.m., more than 9,200 people passed by the casket, said Melissa Giller, chief of staff for the library foundation. The library had prepared for 2,000 visitors an hour for 30 hours. Twenty-seven buses shuttled mourners about five miles from a college, which was shut down to provide parking.

Nancy Reagan, accompanied by Patti and son Ron, had paused earlier on her way into the funeral home as she passed a display of impromptu remembrances. American flags, flowers and jars of jelly beans — Reagan’s favorite treat — were left along with notes, stuffed animals and candles in the spontaneous shrine.

Nancy Reagan, 82, read some of the messages.

“Thank you for changing the world,” said one handwritten note.

Roxanne Kubicek, 42, gave officers guarding the mortuary a card for Nancy Reagan.

“I just wished her lots and lots of love,” she said. “I admired the beautiful love that they have. I told her that their love will last for all eternity.”

Besides Nancy Reagan, Ron and Patti, others attending the service at the library included Reagan’s son, Michael, and his family; Dennis Revell, husband of Reagan’s late daughter Maureen; and Merv Griffin, the veteran entertainer and family friend.

From a bridge over the 118 Ronald Reagan Freeway in Simi Valley, Calif., members of the Los Angeles City Fire Department salute along with members of the public as the hearse carrying the body of former President Reagan passes by. Reagan's body was being taken to lie in repose at the Reagan Library in Simi Valley.

On Wednesday, the former president’s body is to be flown to Washington, D.C. Following a ceremony Wednesday night in the Capitol Rotunda, the body will lie in state there.

Friday will be a national day of mourning, with all federal offices and major financial markets closed. The state funeral will be at Washington National Cathedral; President Bush will deliver a eulogy, and former Soviet leader Mikhail Gorbachev will be among the mourners.

The body will then be returned to Reagan’s library in Simi Valley for a private burial service Friday evening. Reagan will be buried in a crypt beneath a memorial site at the library some 45 miles north of Los Angeles.
