i saw alot of snakes in colorado, i dont think there is much of anything to do to keep them away. maybe run like hell, or stay very still? We were squatting this one place in Arvada by the tracks and first thing when we starting settling in, this 3-4 foot orange/tan/brown snake, at least 6-7' in circumference, comes into the building, like he owns the place. he probably did. i tried to detour him many times with a long plank, and ended up having to seriously maim it. i felt bad, but we had a puppy, and the room was small and there wasnt much else to do, you know? another run in with a snake was further down the tracks, a baby rattle snake! YIKES! but the girl i was with wouldnt let me try to get rid of it, even though it was inhabiting our 'relieving' area...
