The vacation home, which the Republican nominee first visited with his father George, is in a key battleground state: New Hampshire, which neighbors his home state of Massachusetts. But Romney is unlikely to do any campaigning there before his vacation ends on July 4th.
The Post says the family activities include competitive triathlons, football-throwing contests and challenges to see who can hang on a pole the longest. The activities known as the "Romney Olympics." The family also takes on chores from "a chore wheel," The Post reports.
After the daytime sports, which also include tennis and waterskiing, are complete, the adult members of the family convene for meetings, where they discuss their jobs, family-life and anything else of consequence.
Tagg, Romney's oldest son, told The Washington Post in a recent interview that the holiday is mandatory.
"My dad said, 'No, you will make it,'" Tagg recalled during a time he was working for the Los Angeles Dodgers baseball team and thought he would not be able to miss work during peak season.
The $8 million, six-bedroom home includes a boat house, tennis and volleyball courts and a private beach, The Post reports. According to the report, other Mormon families vacation in the area and the Fourth of July is a popular holiday complete with a parade.
