Before leaving Shanghai ...

... we took my parents on a quick trip to the zoo -- with Spring finally seeming to arrive, the trees were beautifully arrayed in blossoms and new leaves.  Afterwards, while my mom & I shopped, the boys went for a bike ride on Shanghai's crazy streets -- and survived! We ended their time here by going up the Shanghai World Financial Center to the highest observation deck in the world ... whew!   And then I was on-duty as a tour guide, taking them to Xi'an and Beijing while Jason continued to work at the dorm.
