You're an idiot.
Rongai is a border town. That's what I said. I have frequented that place a lot.
Rongai is a Maasai name. Nairobi and Nakuru are maasailands. The fact that you believe Kenyans copied the name from Tanzania is the reason I always say Tanzanians would accuse Kenyans of copying them if they breath.
Btw, a few kilometers from Rongai towards Moshi junction there's a town called Enkare Nairobi which is also the original name of the city of Nairobi. Who would you say copied the other in that case?
