Well, I already traveled to US and Canada. They are quite different. In the US I guess they are more consumists and if you like shopping you should go to US. If you like snow, nature, or want listen accents from all around the world, want go see the boreal aurora, I should go to Canada. I guess they are more polite too. But you rarely see a Canadian, you see a lot of Chinese, Japanese, Indians, muslims, etc...
I would like to go to Irish now. I think is more a historical travel, you can see a lot of castles and beautiful old cities.
I also want go the US known treir national parks, like Yellowstones.
Because there are many places that i can choose.
