According to ABC News:
Gov. Mitt Romney's campaign toasted its top donors Wednesday aboard a 150-foot yacht flying the flag of the Cayman Islands. The floating party, hosted by a Florida developer on his yacht "Cracker Bay," was one of a dozen exclusive events meant to nurture those who have raised more than $1 million for Romney's bid.
This is where the "Real Republican Convention" was held, forget the dog and pony show at the stadium in Tampa.
