I have been fortunate to have travelled a little in the past at least (who knows in the future) and really enjoy Italy and Spain. Paris is nice too, but only aspects of it.
One of the things that has helped my wife and I explore is that I have always tried to find a place for us to dance salsa and it has meant we have gone to areas most tourists don't.
I think if possible, everyone should travel just a little outside of their country or culture if they can and expose themselves to how similar we all are in so many ways.
We are hoping to travel to Canada as soon as the boarder opens open again. I don't think it's vastly different then America but it's a start
I have an uncle (if still alive) in Toronto and have always wanted to see Canada. I have never had a strong desire to go to the US though - but I would of course go if I could. I would like to photograph in NY for example.
I think that while not entirely different, Canadians themselves are a bit more (on average) down to earth and relaxed than Americans. Though my experience with both have mostly been hockey players :D
