I've seen a few rattlers out on the trails here in Phoenix, but never really thought I'd encounter one on the road. However, I've only been doing road rides for a couple months, and about a week ago I was startled when I nearly ran over a snake sunning himself on the side of the road! The rule is, the first person doesn't get bit. The first person scares it, it gets coiled up as the second goes by, and the third person gets the strike. I ususually ride 3rd in my Sunday group, and when the leader yells "Snake!" I hit the brakes!
