180222-N-QK571-402 POINT MUGU, Calif. (Feb. 22, 2018) Students from Rio Vista Middle School in Oxnard, Calif., react as their spaghetti bridgehead takes on more weight during the Tri-Warfare Center Middle School Challenge at Naval Base Ventura County. Rio Vista took second place in the event, which challenged students to build bridgeheads that would bear the most weight in comparison to the weight of the bridgehead itself.
