I’ve actually spotted one sitting on the grass at the top of the BIG hill before you get to Sparta on the northbound side, between the boulders. It’s all curb there. It’s been a long time since I’ve seen them there, maybe that’s why; but I always look when I pass it.

Same spot, just past, going south where the lanes come back together at the cut through. Also on the shoulders, north late at night so just as you clear the top of the hill, your toast; and south as you come up the first part of the turn and you crest to the little straight, they’ll be in the grass on the left or the shoulder on the right.
