  We study QCD with two flavors of dynamical Wilson fermions at $\beta = 5.5$
and three values of $\kappa$. The corresponding pion masses are 0.375, 0.324
and 0.262 in lattice units, with pion to rho mass ratios of 0.76, 0.71 and
0.62, respectively. We use the configurations to compute the heavy quark
potential, leading to lattice spacings of 0.110, 0.105 and 0.099 fm, and to
compute spectroscopy for several different valence quark $\kappa$'s.
