It wasn't exactly a "white wedding" for one York couple Friday night.

Amid artificial tombstones and an aisle marked by "bloody" footprints, John Kemp and Liz Caswell said their I do's in a Halloween-themed bash in Girard Park, not far from their Vander Avenue home.

The bride walked down the aisle in an orange gown, covered in fake spiders and complete with a black veil. The groom, with his face painted green, donned fangs and medieval armor, including a two-handed mace and red tabard.

As for those in attendance, the bride and groom had only one request -- you must come in costume. From Mrs. Claus to the Simpsons, guests arrived dressed in their Halloween finest.

The couple -- who got engaged at a Halloween party in 2008 -- say an unconventional wedding was always in their forecast.

"Originally we were trying to do it at the Renaissance Faire . . . but we just kept putting it off and putting it off," said Kemp, who met his future wife in an AOL chat room 10 years ago.

Their next plan was to wed before the Justice of the Peace, before finally deciding, according to Kemp, "You know what, why don't we just do the whole wedding in the backyard . . . just go ahead and have everybody here?"

To close friends and family, though, their decision to have a Halloween wedding didn't come as a shock.

"It's totally him," agreed the groom's close friends Tony Krause, Nikki Krause and Susie Wong.

"I'm not really surprised," said bridesmaid Vanessa Brown, who added that she didn't realize just how serious the two were about the theme. "I should have asked more questions . . ." Brown admitted.

As for the bride's mother, her initial reaction of "Oh no, not that!" was quickly swayed.

"It sounded exciting once we got into it," said Caswell's mother, Peggy Markline, who came dressed in a princess costume purchased just hours before the wedding.

Both bride and groom agreed their alternative wedding was everything they had hoped for.

"It was wonderful," said the now Liz Kemp, before being shuffled off to join the reception in their backyard.

According to Wong, Kemp and Caswell are a "match made in heaven." Or, as Nikki Krause quickly added, "a match made in hell."
