Emma Radacanu won the US Open at the start of her career. I think it’s the only tournament she has won. And given the injuries and challenges she has faced since it’s possible it will be the only one she does win.

Has anyone else ever had a career where the only tournament they win is a grand slam?

The US Canadian border is the longest in the world. Is there a fence that runs along it? Are there official border crossings and do you need to show your passport to enter/leave the country?

Do lots of people live in one country and work in the other? Might a Buffalo resident work in Toronto or do you need work permits to work in each other’s country?
