The six geese are still a honking

Most of my run was after the sun had gone down but it wasn't daylight yet. The Salt Lake Valley is surrounded by high mountings, and the sun sets behind the mountains earlier than it would in flat country. I was on my way back when I say 6 or 7 flocks of geese flying north with lots of honking. They passed me and continued going north for another quarter mile. Then then turned went south and passed me again. I guess they were looking for a place to spend the night. It seemed strange that they went north and then reversed course and went south. Oh well, they know what they are doing.
