Back of Palmersville chippy there's a similar type of deal. Two drain pipes, a wall, and going diagonally across another drainpipe with a metal casing around it - That's the GK. Hours were spent shooting against that wall to beat the GK. To the left were little mini concrete bollard things, those were defenders/the wall to practice freekicks over.
Bottom of my street were some garages, if no one wanted to go in goal we used 2 of the garages as goals, the bricks that seperated the garages were the 'keeper, as were the big long hinges and locks. Cue the 'nah, hit the hinge' ... 'did it f***' ... 'not playing anymore' arguments.
Funny the things you'd do as a kid for a kick about.
