Just go do it!
I went on a the 3-Day Cultural tour with Heather as my guide. I had the opportunity to meet with a Maasai medicine men, go on a game drive of Ngorongoro Crater, learn bout the Iraqw tribe in Karatu, and went with Hunting with the Hadzabe! This was one of the wildest and memorable experiences of my life.
To top it off, it is great to know that my visit to these villages helps to preserve and promote their cultural heritage.
