We report on preliminary results from multi-particle fits to meson propagators with three flavors of light dynamical quarks. We are able to measure excited states in propagators with pion quantum numbers, which we interpret as the pion 2S state, and argue is evidence of locality of the action. In the a0, (0++) propagators we find evidence for excited states which are probably the expected decay channels, π + η and K + K̄.
