Consider yourself lucky you saw Rhinos. You should know that when you go on safari you are in a cage in your car. It is animal territory so you should respect their space. It is their right and ways you should abide by. Stay in your car and wait. Do not disturb them. There are fines if you do not obey rules of safari.. Harami nathi they are protecting them from you and your car. So respect them. Rule of thumb. I am originally from E. Africa hence this advice.
