Chelsea Clinton's Pending Nuptials Rock Rhinebeck

Champagne bottles popped and fizzed on the sidewalk outside of The Rug Garden on Market Street Wednesday evening as a dozen partiers gathered under balloons in downtown Rhinebeck.

"Here's to Chelsea and Marc! Welcome to the Hudson Valley!" toasted one partier, raising her glass in the air.

Shops and restaurants in this small town are celebrating this weekend's planned wedding of Chelsea Clinton and Marc Mezvinsky - some more elaborately than others.

Many shops have hung banners, artwork, or photos in their storefront windows congratulating and welcoming the couple the couple.

"It's very exciting," said Jinnel Rittel, the manager of Cesare + Lily boutique. "These are big people!"

The couple is rumored to be getting married at the Astor Courts estate. The property is secluded by trees and borders the Hudson River. Signs along the outskirts of the property warn people to keep out.

Last week, two Norwegian journalists were arrested for trespassing on the property.

New York Daily News photographer John Roca chartered a Cessna from the nearby Dutchess County Airport and flew in circles 500 feet over the Astor Estate to snap photos of the property, including a newly assembled, large air-conditioned tent.

"It's the only way to photograph this thing," he said after landing.

The town of 3,000 people is now sprawling with reporters and photographers. These days it is not uncommon to see two or three television crews at once on the sidewalks in downtown Rhinebeck, which only has one traffic signal.

"Oh my God, the traffic is crazy!" said Stephanie Winne, a local real estate agent. "We can't even imagine what it's going to be like on Friday."
