Cadbury's marketing stunt goes awry.

Cadbury's Marketing stunt goes awry.

"The 347-year-old historic Old Granary Burial Ground was shut last week after Cadbury's Dr Pepper unit hid a gold coin there as part of a 23- city treasure hunt promotion, the newspaper said on its Web site. People flocked to the cemetery to retrieve the coin, prompting concern graves would be desecrated in the search. "

This is the second time Boston has been at receiving end of a marketing stunt.
