The contest promised a prize to the person whose note went the farthest.
As of early yesterday afternoon, no word from Heidi Kay.
"We don't know anything about the person whose name is on there," Ocean City spokesman Mark Soifer said.
He said she would receive a three-day vacation at "one of the motels" if she is found.
Messages left for several Heidi Werstlers - found through a database and Facebook - had not been returned.
People provided their own bottles or jars for the contest, filled out the entry forms, and put them inside.
The containers went into the Atlantic from the Music Pier at Moorlyn Terrace and the boardwalk, Soifer said.
The note asked the finder to call the Ocean City public-relations department.
Only one other bottle showed up - in Virginia or Maryland, probably in the early 1990s, Soifer said. That person never came forward.
The newly found bottle turned up at the Sanderling Resort & Spa in Duck on the Outer Banks.
