A good friend of mine was in the PC around the same time as the OP. She was in Togo, Africa,
She just returned from WDW recently and we were discussing the African area at AK. She told me that all she could talk about to her Mom and her boys about was the last time she and her DH were there. She said that when she turned the corner into "Africa" she was caught up by the smell of the spices and food being cooked outdoors. She said it really brought her back to her time in the PC. So, when she came up into "Africa" this time, there was no smell. They had done away with the outdoor cooking and such. She was so disappointed that her Mom and DSs couldn't experience that smell, too.
She did say that she went to a man who was playing the drums who was supposed to be from Uganda. She told him that she knew that he had to be from Ghana. He admitted that he was and asked her not to tell anyone. He said that most people can't tell the subtle differences between African peoples.
Anyway, I thought that was interesting.
One of my favorite bracelets was one that she brought back for me from Togo, with matching earrings.
