SNAKE on campus!

I get up to fill my water bottle...stop....i'm sure a prize winning facial expression flooded mine as the quick reacting cook noticed i had stopped dead in my tracks, realizing there was a snake slithering right in front of me. I didn't know what to do; so i just stood there dumb founded, stone still, except for a frantic gaze darting from the snake and the cook. HELP! So it wasn't "that" big, probably a foot and a half or so, grey, and quite a graceful glider. Still though, my moment of short panic was returned by several others as they got up from their pleasant lunches and conversations to steal a peak. A brave soul took a broom and pushed the to the grass, but still inside the campus grounds as oppose to outside; not sure why. So moral of the story, don't sit in the grass and definitely always keep your eyes open, these snakes are far from shy!
