Sorry to be pedantic but you cant "pay nothing"
There can be no payment or free of charge but you can not pay nothing.

The road goes straight past you need to walk along the canal by going through a gate but its easy no more than 200m on foot the bridge will join that road I think

Should feel at home then because that's a bit like being at the Willows.!!

How the hell would you know what it's like to 'feel at home'?!?

Like nobody leaves there cars on streets all over Salford. The point is about paying 4 or whatever quid extra on your match day experience ! why suddenly will cars be vandalised ?

Had a work related visit to Langland Drive today, the big gate at the end is locked . To access the road you can see from Barton Bridge running behind the stadium is via a small gate onto the unfenced and un paved canal bank and then through a narrow opening back onto the road.
Your then greeted by a Manchester Ship Canal Company No Trespassing Sign.
I have no idea wether that sign is still relevant considring the public footpaths that crossed the stadium site have been re - routed.
Maybe a nice walk in the summer months but a February / March evening hike dos`nt look good.
