Everyone had a great time last Saturday on the Illawarra geological field trip organized by Creation Ministries International. The weather was perfect and the enormous waves made the Blowhole at Kiama look like a fireworks display. It was also fantastic at the next headland, Bombo Point, which we visited in the afternoon. The people were [...]
