LAS VEGAS -- Churches, banquet halls and other wedding venues across the country were extra busy Sunday as couples seeking a perfect 10 rushed to tie the knot on a once-in-a-century milestone: Oct. 10, 2010.

In Las Vegas -- long a destination for weddings -- one marriage license bureau extended its Sunday hours from 6 p.m. to midnight to accommodate the rush.

Wedding-related businesses said the day was perhaps the most sought-after wedding date since July 7, 2007, when the lucky 07-07-07 marked the calendar. Some 10-10-10 couples even chose to take their vows at 10 a.m.

One pastor in Nevada took the rush airborne by planning to join 30 couples at various venues Sunday and aboard a helicopter through the buzz of a headset.

"This is kind of a neat way to spend my retirement years. It keeps me in good health and keeps my mind alert," the Rev. Jim Hamilton of Henderson's Sunrise Community Church said.

Megan Powell, a 26-year-old who married a nightclub and restaurant operator, said her Las Vegas wedding was "a once-in-a-lifetime opportunity to get married on 10/10/10."

"That day will never happen again," she added.

Her new husband, Scott Frost, called it "fun" that "we'll have something unusual in common with a big chunk of people."
