The daughter of the former president and the current secretary of state is set to say "I do" Saturday afternoon or evening at Astor Courts, a private Rhinebeck estate neighboring the Hudson River.

Signs of the event began to pop up Saturday morning in the village and as the day wore on, the pace picked up.

Three black Lincolns were parked outside the Delamater Inn with the drivers dressed to the nines. And clerk Gianny Andreini at the Rhinebeck Smoke Shop said he sold a couple of $30 top-of-the-line cigars Friday night, which is something that doesn't happen every day.

Clinton's nuptials to Marc Mezvinsky are expected to cause road closures and possible traffic delays as media outlets from as far away as Australia and spectators flock to sites where guests were seen checking into Friday — mainly the Beekman Arms and Delamater Inn.

As hundreds of reception attendees sip cocktails Saturday, the weather is expected to be in the low 80s, dry with low humidity.

Chances of viewing the bride on her big day are slim to none. Security will keep Astor Courts on lockdown and gawkers at bay.

The Federal Aviation Administration confirmed local airspace would be closed temporarily (for aircraft flying under 2,000 feet) while boating on the Hudson will not be restricted, but police will be patrolling, Kranik said.

The main intersection in Rhinebeck, known as the "four corners," resembled something of a block party Friday, as camera-armed people waited and waited to snap a shot of a celebrity.

Perhaps the most famous of all guests, the father of the bride, Bill Clinton, created a small frenzy in the afternoon as he strolled down Montgomery Street into Gigi Trattoria for lunch.

The atmosphere was buoyant even after Clinton was last seen getting into his Secret Service escort vehicle around 2 p.m. To add to the festivities, men wore Bill Clinton masks and others held signs that read, "Seat me at Oprah's table."

Businesses had their part. The A.L. Stickle variety storefront was decorated with kissing stuffed animals — one wore a veil.

The Rug Garden held a champagne-and-cake reception for the less fortunate who didn't get their Clinton-Mezvinsky invites, while the store's owner, Deborah Belding, blew noisemakers.

"We're having our own party," she announced. "We weren't invited."

Shortly after, The police shut down her street celebration.

Retiree Ray Green of Staatsburg lounged in a folding chair, hoping to see Oprah. His companion, Joan Tallman, said she saw "girls Chelsea's age going into the Beekman Arms carrying dresses."

Bittersweet Bed and Breakfast owner Edith Thomas said she's was expecting "a mix of actors and politicians" who are attending the wedding to check in at 3:30 p.m.

Earlier Friday morning, Clinton's event staff dropped off "very fancy, gorgeous baskets" for each guest.

Around 4 p.m., a white SUV limousine followed by a black stretch limousine drove by the Beekman Arms as a speculator shouted out, "That's her. That's Oprah." Around the same time, workers secured the Beekman Arms' front entrance and lawn with a white fence. Secret Service members popped in and out throughout the day.
