Like Serengeti sardines This hippo pool lies 50 yards from a dining area at the Serengeti National Park river camp where Terry Powers and his fiancee, Jennifer Rusin, spent eight days in fall 2006. The hippos resemble rush-hour commuters on an overcrowded subway car -- and look just about as jammed for elbow room. No wonder Powers, of Irvine, said the big Tanzanian neighbors were not that neighborly. "You'd go to the water's edge and they'd grunt and jostle, as if saying, 'You think you're gonna come in here?' " He used a Nikon N65 for the shot.
