What do you do?

So....what do you do when you show up at a sample site and find a Buffalo that doesn't want to move?  

Then once the Buffalo moves, you see the fattest Nile Crocodile that you've ever seen in your life...

Then you see the other HUGE Nile Crocodiles sunning themselves on the bank...

Then you notice the Hippo...

After the Hippo leaves the water...you then notice him hiding in the bushes...watching you (middle of the picture....you can just see big ole head sticking out from behind some bushes)...

You sit there for a while and think....and observe...

You watch their movements and be very, very careful...

Nobody ever said it would be easy.  :)
