As fall begins, I spent a few days in Prague. Of course, it was hard to miss the stunning Prague Castle (not to mention the beautiful 14th century Charles Bridge). Prague Castle is said to be the world’s largest castle area, with three courtyards spread over eighteen acres. Along with admiring the beauty of the city, I also admired Roger Federer's singles and doubles win at the Laver Cup. It was the first (and will likely be the only) time Roger played doubles with his rival, Rafael Nadal, and it was a joy to watch the camaraderie between the two throughout the weekend!
