Certainly do Foxy. The opencast was a field where we used to play that originally belonged to Fails Farm, if I'm not misstaken. It was between the colliery rows and what eventually became North Ridge. One of the things I remember about the opencast was a small red brick building, just up the road from Raisbeck's Garage, where they used to put new treads on enormous tyres. Possibly from the trucks on the site. The smell was horrible.
