GROVE CITY, Ohio (AP) If one bride felt lighter than air in her wedding gown, her groom certainly felt like air itself as 19 couples renewed their vows near Columbus.Sheila Smith's husband, Bob, had to go away on business and couldn't make the Valentine's Day recommitment service at Grove City United Methodist Church. So friends brought a life-size inflatable doll to serve as a stand-in. They dressed blow-up Bob in dress pants, a shirt and tie, and taped on a head-shot photo of the real Bob Smith. His wife was blown away, because she thought she'd only be serving as matron of honor for four of her friends. After Sheila Smith phoned her husband to tell him about his air-filled alter ego, she wiped away tears as she told how he laughed so hard he couldn't speak.
