Five things we're all wondering about 1 Kai Tak to be redeveloped in HK$100 billion plan ... I guess the government can focus on other projects now that West Kowloon and the Macau bridge are completed. 2 Fake 100-yuan notes on the increase ... They're as worthless as your Wall Street investments. 3 No MTR station for Happy Valley ... The people living there are happy enough. 4 Hong Kong voted freest economy in the world again ... If we were any freer, there would be pirates in Victoria Harbour. 5 Winter monsoon continues with cold and dry weather ... The only thing more frozen is our pay.
