This post doesn’t have any images sadly but I am writing it so you can go online and check something out.  Nancy and I took a walk along the shoreline in Hayward.  We saw something strange out in the water and, when it happened again, we realized that it was a pair of grebes running across the water.  We Googled this and it turns out it is a mating dance that grebes do.  They pair up and then start slapping their feet on the water so quickly that they can actually run across the surface in formation.  It is called rushing and is quite amazing to watch.  I can’t show you anything myself but do look it up.  It is crazy stuff.
