Think I have shared with somebody about learning roller-blading in this forum.
Anyway, to get somebody to teach you roller-blading isn't difficult. There is a middle age uncle roller-blading at East Coast Park. I have met hima couple of times while I was doing long distance jogging along East Coast Park!
This man is not difficult to spot him. He is really good is blading and can do lots of 'ice-skating' stunts! Do not worry, he is will to teach anybody for free-of-charge! Just make a friendly approach to him.
Good luck!
