Ten years later, Cara Walker can still close her eyes and stroll the dirt streets of Moshi, a Tanzanian city within sight of Mount Kilimanjaro.
She remembers wandering through shops and open-air markets with no agenda, browsing to learn. Bougainvillea bloomed. Kiswahili music played. Chickens clucked, and babies cried and laughed.
“Your senses are constantly engaged, if not borderline overwhelmed,” Walker recalls. It was "a surreal and beautiful experience.”
