Failing that, find a flat, gently sloping area, put on your skates and
all safety protection gear - even tie a cushion to your butt, and get out there and give it a go. If you've ever skied or ice skated, it isn't so hard.
I taught myself to ski, with a similar method, on a gentle slope - it's just a case of getting the feeling and the confidence.
