I was hiking in central Kentucky today and stopped to take some flower macro shots next to a creek. This spider was going back and forth between some of the flowers. I couldn\'t get a very good shot of it, but I hope these pictures are enough to help identify.

I sort of hope it wasn\'t one because I saw a lot of others out there today and really don\'t like the possibility that I brought one home on my clothes.
