It's a tradition that all navy bases worldwide have a mast and yardarm installed to display flags - just like on the wooden ships of old. It looks good, traditional, and is a nice touch. Someone stood back and noticed how these resemble a Christian cross at the base in Jeddah. So off came one of the arms. Now it's a pole with one yardarm to the side.
Ambulances have a crescent moon replacing the traditional red cross.
And here you thought that I was the paranoid one all of this time. On Globe Road outside of Jeddah, is the gigantic globe that we foreigners identified this highway with. It lights up at night. Little bulbs all over it mark those areas on the planet that indicate the proliferation and spread of Islam worldwide. Think about it's significance.
