I had one chase me off the 9th green at Buffall Run Golf course (104th and Chambers) a few years back! It scared the hell out of me as I walked up to my ball just off the rough and saw a wicked set of teeth coming out of the waist high grass hissing! I believe i set a course record for fewest steps back to my cart!

Sitting in the cart, I watched it cruise back and forth around the green before disappearing back into cover. Those things are mean lookin' little bastards!
