I've managed to visit all 50 US states but only four Canadian Provinces, Ontario, Quebec, New Brunswick and Nova Scotia. Also 6 countries out the US for a day or more.. But since the US seems unlikely to add a new state soon, I probably won't have a 51st state to visit in my lifetime. BTW, speaking about Niagara Falls, I had a great grandfather who suttled back and forth from central Ohio to Niagara Falls. He worked in paper mills and even owned one for a while until he started hitting the bottle. His father also worked in papermills in Scotland, Ireland and the US.
