I do for fun haha, not seriously or anything, even though it would be kinda fun to start. They're so fun though to just fuck around on, I fucking own on them haha, and playing road rage with them is awesome too, I got my finger squished real bad a few years back doing that because me and my friend were going head to head trying to ram each other off the road and I flipped him off and then he rammed into me as i had my finger out, and somehow my hand got squished in between the two carts or something. It hurt, a lot.
