Back to The Gambia?

Been away too long - but how to stretch the money for the fare? Every penny GOES receives in donations goes to help people in The Gambia - nothing is deducted for 'expenses'. We're having a furious counting of personal money to try to raise enough for at least one of us to travel. We would like to see the tap installed in the clinic, the open-air classroom in the school completed. We're searching the internet and local travel agents for the cheapest deal. Thomas Cook have been very helpful in the past ...
There is always this dilemma: - which is better for The Gambia - us going there to see first hand exactly what needs doing or sending the money we would have spent on travel to a clinic or school? Maybe the British government will double my pension! Ah, well. Back to Google!
