I am now in Cape Coast Ghana; I arrived from Shama on a small van, maybe called a TroTro for 1200 Cedi. There many obtuse and convoluted names for the same thing on the planet, it becomes tiresome. I am a strange collector, thus I have a list of types of transportations on the planet, and hopefully one day it will be a list with a photo next to it.
The cost to travel with Tro Tro between small cities is less than a bus ride in a major city on the planet. It is cheap, too crowded, cultural, and an experience that defines any country. Traveling with the locals will make you know the country.
