I did fly to Hong Kong with the Volley ball team. It was a bit hard to wrap my mind around this concept. Instead of throwing the kids on a bus and driving an hour to Boulder for competition, or even overnight to Glenwood Springs for a xc race in Aspen, we MET the kids at the airport, dressed in uniform we (7 coaches and 48 kids) flew to Hong Kong. Coaches stayed at a hotel downtown and the kids each stay with a host family of a kid from the Hong Kong school.
Now although I went to Hong Kong, I mostly saw the school and my hotel room. Speaking of, my hotel room was way up on the 35th floor and was about 8 feet by 8 feet square. My ankles hung over the side of the bed. There was no room for anything in this room at all. It had a killer view, though. I definitely want to go back with Bridget when there is more time to explore the city. We played 6 vball matches in 3 days.
Nonetheless, Hong Kong is quite a city. Quite different from Shanghai.
