Whilst in the Navy we stopped in the Cape Verde islands for fuel whilst on passage from Barbados to Sierra Leone.
The islands are, in my humble opinion, a **** hole. The best place we found to eat was at the local petrol station....a shell garage no less.
They take euros, dollars, pounds...whatever you can offer them and the islands are reminiscent of other african countries.
At the time we were there thought the sahara winds were in full flow so you were lucky if you could see more than 200 yards ahead of you due to the massive sand storms, and everything had an orangy tint to it as thought it was a sepia photo which didn't aid it's appearence.
