Summary: A rowing row on the Thames... the annual competition between Oxford and Cambridge Universities is derailed by a mid-river protestor. Also on the show: a lament for a California State Park slated to close by July. Seventy of the state's 209 parks were scheduled to close as a money-saving measure, but sponsors have been found for nine of those. For the rest, the wholesale closures are prompting soul-searching about the ignoble fate of a rich natural and historic legacy. And later, researchers are looking for new ways to diagnose and treat concussions in children.
