hahaha... okay... i'll try to answer... and for the record you should really get in touch with your boy, sounds like you miss him...
it's mostly christian from what i can see... which is kinda sad to me really... but i have met some muslims, some athieists... i would imagine it's all about your circle and where you run just like anywhere else... but also, in tragedy (not necessarily Ghana, but i'm thinking of the Liberian Refugees, the Togo Refugees, and the Chadian refugees here) one reason why christianity is so pronounced is cause a lot of the food aid given in tragic situations were from christian programs... same with the free education, clothing and refugee camps... i suspect they saw the opportunity... meaning the christians.
