Anatomy of a Presidential Candidate's Vacation, Part II

From CBS News' Maria Gavrilovic:

(HONOLULU) Barack Obama worked out with his wife and toured some favorite local spots on the second day of his weeklong vacation.

Obama and his wife, Michelle, worked out together at the 24 Hour Fitness gym, where they tried to burn off the calories from their late night dinner on Saturday. An aerobics class stopped their work out to wave to the famous couple as the left the gym.

The Obamas, with their daughters Malia and Sasha in tow, later visited the Valley of the Temples Memorial Park on the eastern side of Oahu. The park commemorates the first Japanese immigrants to Hawaii and features a Buddhist temple. They also stopped at Aloha Tropical Farms - a Macadamia nut outlet.

Longtime friend Bobby Titcomb hosted an evening BBQ for Obama and his entourage. Titcomb played basketball with Obama at Punahou High School in the late '70s and the two have remained friends ever since.

Although Obama spent his Sunday relaxing, his Chicago office was working away on a new ad jabbing at John McCain.

This morning they released the ad entitled, "Embrace", which features McCain as a "Washington celebrity." The ad has clips of McCain on Saturday Night Live and video of him embracing President Bush.
