  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 is evidence of locality of the action. In
the a_0 (0^{++}) propagators we find evidence for excited states which are
probably the expected decay channels, pi+eta and K+Kbar.
