An old college friend of mine, Sam Singh  http://singharoundtheworld.typepad.com/blog/, took a journey around the globe going to the key points of interest to him that he felt were 'must' see and do's in his lifetime.  He tracked his travels and adventures in his blog posted preiovulsy.  He called it his 'World List'.  So lets see if we can come up with one of our own.
