Hello Lucy. I believe there r , or were, a bunch of stilty people allied to 'ryde extreme' or similar.
Failing that there is also http://www.jurassicjumpers.stiltsmedia.co.uk/forum/index.php
This is a group that hang about in the Hants/Dorset region. Do , at the moment, most of our stuff in Portsmouth. So if you r near a ferry that goes there...come on over and say hi. Failing that, post some pix showing US that the IoW is the place to bounce about
