Saw some of the most amazing landscapes and animals I will probably ever see, and learned a great deal about them. Tsavo West/Chyulu Hills National Parks in Kenya and Kilimanjaro (we just did a day hike) in Tanzania were my favorites.
Although the classes were exceptional and I learned quite a lot within the advertised topics, I think the part that will stick with me the longest is experiencing, observing, and reflecting on humanity and society at many different points. Overall, I learned a lot, learned that there is so much more out there, but also that there is so much to live and see wherever you are.
