Zambia is a lot more advanced than Uganda. Some obvious things that I saw that I haven't seen in Uganda were consistent use of stop lights, street signs, stripes on the road, and a lot less litter.
War surely messes up a country, and Uganda is living proof.
The people in Zambia are beautiful and kind, and their capital city, Lusaka, was very nice. We lived in Lusaka a little over a week in a dorm-like building with rooms on either side of a hall and 2 showers for each sex at the end of the hall. Karis, Caleb and I stayed in one room, and Doug and Kylie stayed right next door in another.
We had fans, constant electricity, cold mornings and nights, and beautiful days! We liked Lusaka, but bush camp was even better!
