How crowed can Tanzania be

One day I was traveling across Serengeti, I used a car to drive from Kilimajaro, that's why my car was not an open vehicle. It was nice, driving through this wide land, open enough to be able to see far away. It was a quite moment, nobody was around.... at least that what I thought !

I reached a wonderful cooler part of the Serengeti, up in Western Corridor, near the Grumeti River.
Hey, someone is arriving...

HOW CROWED CAN TANZANIA BE ? 

AND GRUMETI, TOO 

.... WOW !

 Ok Let's have a drink, now !
