Although personal safety is not a BIG problem, I read everywhere before I came that it Accra is quite safe, so just felt compelled to let others know that I was mugged at knife point around the airport residential on my second day, and we have heard of SEVERAL other armed attacks around there especially. The attackers are usually on motorbikes, and circle the area looking for a chance to pick you off. Although I still believe Ghana is relatively safe, I wanted to say you need to excercise more than normal caution.
