Dave Weinlick has three small requirements for his future wife: She must be spontaneous, carefree and available to get married Saturday.

The 28-year-old has the rings, the minister, the musicians, his tuxedo and a reception all arranged. But he won't know whom he'll meet at the altar until just before she walks down the aisle.Potential brides are invited to attend a Weinlick's "bridal candidate mixer" the day of the ceremony, where the groom's friends will screen them and their friends will screen Weinlick. There will be a vote, and Weinlick will marry the winner.
