Yes limiting the number of people is good, security going in and out keeps tight control in the area, Mission Rocks only allows 25 cars at a time, those going for a day fishing normally go in early.
Drought affected the area badly, it was shocking to witness! Before going into the area we checked, then took bottled water up with us, fortunately the place we stay at has a borehole so 5 liter bottled water containers were given to the staff at accommodation who carried water home with them every day since they had no water coming into their homes.
Most of the Rhino in this area no longer have horns, to save their lives the horns are removed, the young family of Rhino we saw still had horns perhaps staff will wait till the little one is a bit older before removing the horn.
South Africa has become unruly, visitors do need to be cautious, my love of the country knows no bounds, it is home.
