This is called Basse Garage because here you can only get cars going to Basse. Basse is part of the Gambia but is located far from the capital, Banjul, about 320 kms distant. Wheelbarrows with different kinds of items for sale are usually found in this kind of place as well.
According to Wikipedia, "Serrekunda (or Serekunda) is the largest city in The Gambia, lying southwest of Banjul. Its population as of 2006, was 335,733 people. Although Banjul is The Gambia's capital, it is on an island and cannot grow further, making much of the growth in Serrekunda."
