A result of Keel and McKernan states that a hypothetical counterexample to the F -conjecture must come from rigid curves on M0,n that intersect the interior. We exhibit several ways of constructing rigid curves. In all our examples, a reduction mod p argument shows that the classes of the rigid curves that we construct can be decomposed as sums of F -curves.
