Classical solutions of elastic strings (i.e., strings with actions which depend on the extrinsic curvature of the world sheet) are studied to determine Regge trajectories. For open strings, our classical solutions are identical to those for the conventional Nambu-Goto action. However, for closed strings, new solutions give nonlinear trajectories that include finite-energy, static configurations.
