My digital camera is out of the shop -- thankfully. Weekend trip to Xian.

Good day today running all around the city with my boys. Got badmitton set -- played at a badmitton staduim. Went to swim lessons.

Catherine and the two Pitt Grad students really had a lot of hard work teaching today. China is getting their value out of them. The class with 13 -- all sharp as a whip -- often is filled with 20+ students.
