The Fall-time Arachnid

My wife is terrified of them but I see them as a good sign. The Tarantulas come out the same time every year looking to mate. You rarely see them any other time of the year and they are a clear sign around here of approaching winter weather. Some years, they all come out of the ground at once and you can see thousands crossing the roads. A rare phenomenon that I have not had the opportunity to see. They can show a threatening display if you get to close but I dont think I have ever seen them bite a person.
