San Diego's oldest park (built in 1850) has the feeling of a Spanish or Latin American plaza. Workers on lunch break play soccer and throw Frisbees on the grass in the center while office types in suits and tennis shoes parade around the broad path that circumnavigates the roughly one-acre park. The less active lounge in sun on the fringes or in the shade of four enormous Moreton Bay fig trees. There’s no bay view, but that’s kind of the point. It’s a sort of green cove in the concrete ocean of downtown.
