Sandbars

They are irritating. We always have to be on a constant lookout
whenever we are going somewhere. When we were getting into this place,
the sand bar and reef were both basically invisible. We kept having to
slow down, and speed up, and loop around, and stop, and mearrgh! At
least we have the help of polarized sunglasses and charts. Without
them, it would be impossible.
