I used to skate a lot when I was younger, now I have no time anymore but I should buy new rollers and restart again !
I'm not and did it a few times. It was really fun. And if you're fed up, you can stop whenever you want.
I haven't been to it this year but I'll try to go later... And believe me, you should try you won't regret !
Rock & ROLL !
