i havent passed Boons in a long time. used to use the road between Magaliesburg and Koster (R503 i think) to go to Zeerust via Swartruggens, this was before the road between Koster and Swartruggens got untarred and people had to drive on gravel.
I only know Boons from the high school on the one side of the road and the silos on the other side of the road.
