[mou] Need help identifying snake

[rdunlap at gac.edu]

I know this isn't a bird question, but I assume there is someone on  
this list with more experience with MN snakes than me. So, I need such  
a person to help identify a snake I photographed this afternoon in Le  
Sueur County. It was larger than a Garter Snake, about an inch and a  
half in diameter. It was uniformly dark green on the upperside and a  
lighter green on the underside. It was around 3.5 to 4 feet in length.  
Let me know and I can send you photographs of the snake.
