I think that's a big deal. There aren't many sports that America can claim inventing 100%, but Roller Derby is one of them, and I think that's neat! One time my friend said that there's a reason America sucks in the Olympics at sports like curling and shot put. It's cause we reign at the COOL sports like surfing and snow boarding. And now, we can add Roller Derby to that list! Not to mention, almost all the skates in the world are made in America.
Finally something you can be proud of! America invented Roller Derby!
