Nancy Hall and Steve Bushell will literally take a plunge into matrimony Saturday.

The couple was selected as one of seven to wed at the 200-foot-tall peak of Six Flags over Georgia's mammoth steel roller coaster - Goliath.

"I didn't even tell my fiancé we were going to do it, or that I signed up" Hall said. "He kind of just found out after we were selected."

Bushell proposed marriage about a year ago, and the couple had not set a date yet when Hall, a second-grade teacher at Rocky Plains Elementary, logged on to the Six Flags Web site and entered them into the Thrilled Ever After contest.

She said if fate decided that July 7 was to be their wedding date, she would go along with it.

Seven couples out of more than 100 were randomly selected to be married on the ride by the Cobb County Justice of the Peace at 7 a.m. tomorrow while friends and family look on from the platform.

The couples will be hoisted to the first drop of the coaster where the ceremony will occur.

"Their words exactly were 'you say I do, and we push the button,'" Hall said.

Kay Jewelers will provide wedding bands to the couples and Saavi Formal Wear provided tuxedo rentals and 25 percent off of gowns for the lucky couples.

A reception in the Pavilions area featuring a seven-tiered cake and DJ will follow the ceremony.

Couples are then invited to enjoy the park for the rest of the day.

Hall and Bushell met when they hosted a karaoke night together.

In December of 2004, tragedy struck when Hall's family was in a terrible car crash outside of Miami on their way to a family cruise. Hall's 6-year-old daughter Maison-Elizabeth died at the scene. Her husband, Mark, succumbed to his injuries after a few weeks in a coma.

After the accident Bushell supported Hall with friendship and by taking her son Case, now 9, to Boy Scout meetings.

A romance blossomed from their friendship.

The ride travels at 70 mph and lasts for 3.5 minutes. It features zero-gravity floating hills and drops, a massive spiral section and high-bank turns.

"I won't chicken out, but I have to make sure I don't cuss when it starts going down hill," Hall said. "That would be bad to do after saying 'I do.'"
