i go past this about 2 to 3 times per week and i have never yet seen a game being played and that includes the current school holiday.
although not marked out the grass is always cut short to enable a decent game to be played. talking to born and bred dovorians they always say how they spent most of their time up the heights usually messing around in and around the fortifications during school holidays yet i have not seen one up there so far this year.
