Maybe, maybe not.
I was once out on a reservation in Arizona, and saw a western diamondback slither out across the one lane, dirt road I was on. I pulled the truck to a stop when I saw that his head had crossed the road, just about the time that his tail started making the trip.
Most of the shakey tails I run across are in the 3-6 foot rang for the most part. I would imagine that for a critter to get that big, he'd have to have learned early to stay away from people habitats for most of his life. With that in mind, I'd have to ask, how recently was the golf course put in?
