I remember growing up and watching roller derby. Now if you don’t know what it is, check out this Wikipedia article explaining the origins.
I have to say that I did not even know that it still existed and was only a fad. But a few years back we found out a friend of ours was on a local team.
After our stunned looks washed off our faces it was actually quite intreiging to find this out.
I’m not sure that this fact will make me pick up the sport either participation or watching. However it is noted that the IOC was looking to add it to the 2020 Olympics as an official sport.
