Penn State Survivor update: Rosenberger and Koror win again

Rival Ulong tribe won the reward challenge at the start of episode six of "Survivor: Palau," giving the remaining members of that tribe a much-needed morale-boost. Penn Stater Ian Rosenberger was one of the members of Koror tribe to sit out the reward challenge, to balance his team's numbers against Ulong. Rosenberger once again was strong during the immunity challenge, however. For the immunity challenge, each team was given a foot locker with the other team's flag inside. They were given all day to make the chest impenetrable using a rope. During the challenge, they had 20 minutes to swim out and retrieve three bundles of wood and more rope, with which they had to make the foot locker even more inaccessible. Then, the tribes switched places and worked to break into each other's foot lockers. The first tribe to retrieve the flag from the other tribe's box and raise it up the flagpole won immunity. Rosenberger's skills -- both in the water and in untying knots -- aided his tribe and helped them win immunity for the sixth consecutive episode. Rosenberger and his tribemates all will move on to episode seven, which will air at 8 p.m. Thursday, March 31, on CBS. Roseberger, 23, a native of Ambridge, majored in agricultural extension and educational leadership at Penn State, and served as student government president.
