Snake number 1

 I went to the park late this Monday morning, but my back would allow me to run 1.2 miles on the trails.  I tried again this evening and was able to add 2.3 miles, for a total of 3.5 miles.  During the brief time on the trails this evening, I encountered a large black snake (about 4 feet), laying across the trail.  I'm not sure what kind of snake it was.
