Unless you are playing at Pollsmoor Bowls Club or get incarcerated, you will not get a view of this club as it is on the far side of the prison.
Even from the residences on the far side you won't be able to get a glimpse as the access road is too far.
I have played here a few times and they did a lot of development for younger bowlers (under 45's).
You don't need to work at the prison to be a member of the club.
