because speaking truthfully gambia doesnt have too much tourism value , neither is it a developed country due to which you can estimate its value
though i suppose letting it drop is stupid but i am sure the total torusim earnings of the countery is not 20000$ and that too is only earned due to the wild life heritage found overall in the african countires
well thats just my view you can differ with it or stick with it
( dont stick too hard
)
