THE Operation Santa Claus 1994 charity fund continues to grow with yesterday's total reaching $2,060,430. Santa's mailbag yesterday contained cheques of $49,500, with the biggest from the Hong Kong Ladies' Circle No 2 Kowloon. The figure is bound to soar in the next 10 days with several big projects designed to boost the fund. This afternoon, a group of auxiliary police officers will hold a sedan chair race. Tomorrow, collections will be made in the trading hall of the Hong Kong Futures Exchange in Central. People donating $500 or more by today could win two United Airlines return flights to San Francisco. The draw will be on RTHK Radio 3 tomorrow.
