These spiders are all over the rocks where we fish. Most are the size of a nickle, but once in a while we get some big ones. This was about 3.5 inches across. About the diameters of a Pringles can or the palm of your hand.
This guy crashed a big orange streamer about ten minutes before dark. It was an absolutely great night. No wind. No people. Had seven or eight fish crash the stramer as it moved down the bank. Only got the one in though. Full moon.
