Abstract: Let X denote the plane, or the closed half-plane, and let $ T:X \to X$ be a self homeomorphism which preserves orientation and has no fixed points. It is proved that, if A is any compact subset of X, then there exists an unbounded connected subset B of X which does not meet $ {T^n}(A)$ for any integer n.
