I remember people used to rave about Jimmy Young's camps. I used to watch him teach at the Palace - he seemed to know what he was doing. Gary Beacom came to the Palace once, and Lorna Brown. They both seemed to puzzle people a bit, though I've liked what I've seen of them on YouTube.
This may be all wrong but I'm not sure I really need lots more input. I've had years of it and I like to think I am getting better results by making sure I am mindful when I skate, enjoying it, and doing it with music I love in places and at times that make me feel positive. I could do with someone to film me now and again, or a big mirror.
