I can't really be much more spesific with its exact location as im not too sure of the area once off the railway but i see it as i go from stalybridge to mossley station, i think if you follow the road that runs at the side of the railway line from stalybridge to greenfield you should be able to the see the site as it is quite high up. it looks like there are hundreds of vans on it so the locals may be able to help. my parents used to store there van on a storage area which is on the marple side of werneth low right at the bottom of the hill, you get to it through romiley as werneth low is too steep, but from memory the access road to this site is also very poor. hope you find somewhere soon.
