Crossed the border into Senegal from Gambia overland. This was not much more than a few donkey and carts + some cars. Most people were crossing on foot back-and-forth over the day only to work on the Gambian side and then heading back home again after a days work. We set our aim for Fathala Game Reserve close to the border. There were at least two-to-three additional invisible "borders" to cross once inside Senegal controlled by local groups making their living from extorting money from passing vehicles. Few things never seem to change in the remoter areas of Africa.
