Suppose τ\tau is a train track on a surface SS. Let C(τ)\mathcal C(\tau) be the set of isotopy classes of simple closed curves carried by τ\tau. Masur and Minsky [2004] prove that C(τ)\mathcal C(\tau) is quasi-convex inside the curve complex C(S)\mathcal C(S). We prove that the complement, C(S)C(τ)\mathcal C(S) - \mathcal C(\tau), is quasi-convex.
