Great topic for the Leeds area, nice one.
I've been bashing at nunroyd quite a bit lately. Plenty of dog walkers around though, get some good chases from them, although not ideal.
Pretty gutted that Yeadon bmx course is out of bounds, would make a sweet track. I run nitro so no chance getting away with anything there.
Good suggestion about getting on at the council for a dedicated track, never easy getting them to do anything like that though!
