I am following you!
I want to ask you what is the biggest challenge you've encountered while travelling to Africa. Having been there myself (Morocco and Mozambique) I think the sanitary one is what caused me a culture shock. I didn't mind taking buses at 5 am as much as I did staying in a hotel with no running water and a cholera epidemic in town.
Also, how often were you asked for money? How much does the percentage change from country to country?
Keep up the good work!
