Subject: Towers and other observation places

Hello everybody, One of the best ways to get the lie of the land and to see a whole city within its landscape is to go up an observation tower. It's usually one of the first things I do (if there is one) when I go to a new city. So I've been up the Eiffel Tower, Seattle's Space Needle, towers in Vancouver, Calgary, Sydney, Seoul and of course the Empire State Building. Do any other travel-ziners have any faourite towers? If so which ones. Patrick Horton, Melbourne
