  We describe recent results concerning the behavior of lattice QCD with light
dynamical Wilson and Staggered quarks. We show that it is possible to reach
regions of parameter space with light pions $m_\pi\approx 0.2/a$ using Wilson
fermions. If the Hybrid Molecular Dynamics (HMD) algorithm is used with the
same parameters it gives incorrect results. We also present preliminary results
using a higher-order integration scheme.
