Just another little correction - from McGrath above 'he ..later got drowned trying to swim the Niagara Falls' it ws actually the rapids below the Falls that he was trying to swim in. - We were in Niagara last summer and there is a boardwalk alongside the rapids -which are wonderful but absoulutely fearsome! I was told that rapids are internationally graded 1-5 in order of severity and the Niagara ones are uniquely grade 6!
