off A-4 Portway Bristol

I have just discovered a new location in Bristol!! This must be the best place around, very discreet and quiet. Where?...Follow The Portway which is part of the A4, which links central Bristol with its port at Avonmouth. Turn of for the Lamplighters pub, which is now boarded up, opposite the pub turn right along a wide footpath, walk! 60yards and there is the first location, a great little spot under a large tree, even has a low lying bough to bend over! Or an alternative to this is carry on a further 40 yards this leads to Lamplighters Marsh where there is a discreet and quiet area. I really do not know why this is not popular as it seems the ideal spot. There are some great blackberries to be picked also!
