It's based in my mind (but not an actual likeness), of where we used to have a 'kickabout' in the local park when we were teenagers...
Here's a photo of the location - it's called 'The Dell' in Priory Park, in Southend.
Odd really, as I was a Saints fan...
There were wooden stantions in those days, going along the path, with roses wound around them. But now they're gone.
We used 3 stantions as the goal width, with the middle one fondly known as 'the defender on the line'...!
When the park keeper turned up, we had to suddenly pretend we weren't using the rose stantions as goals, and just pass the ball neatly between us, and doing keepsie-upsies.
Then when he went, is was game on again!
I suppose if we played there now, we'd be tempted to use those two little trees as goal posts.
...not sure if they would survive to many shots against the post though...
