The LSV is nearer to the East Lancs Road where the old BARLA training facility used to be. As it is now, if you drive down the A579 from the East Lancs Road, you will first have the LSV main stadium on your right, immediately followed by Leigh East's new gaff and then cross the canal bridge with Leigh Miners immediately on your right hand side.
Ah, my mistake.
I visited the old Hilton Park ground many times over the years but haven't been to Leigh for ages, well since they dropped from SL. There used to be an amateur ground somewhere between a quarter and half a mile further out of town from HP(leigh Miners?) which we always used to pass on the way in, is that where it is?
Think it's a little strange to include grounds in this list that are still standing (Gigg Lane, Deepdale and the like), so of grounds that no longer exist I've got the following rather short list;
Hilton Park (as you'd expect - I played in one of the last 3 games there in a curtain raiser against the GB All Stars side)
Central Park (as much as I hate to say it, I agree with others that that place had a tremendous aura about it. Still a little strange driving down from Scholes and seeing Tesco instead of the floodlights)
Knowsley Road (ended up going to the last game there, glad I did although I'd been a good few times previously watching Leigh and neutral games)
Wilderspool (only a couple of times to watch Leigh, one of which was a Challenge Cup Quarter Final in 2001. Technically still standing but I believe in a bit of a sorry state these days).
Have also watched Blackpool at both Bloomfield Road and Fylde RU before their demise and Chorley at Victory Park.
All three of those grounds still exist though so I'm breaking my own rules there!
