Results for the spectrum and the F and D parameters are obtained with precision similar to that in the quenched approximation. Present data for m{sub q} {ge} m{sub s} show measurable effects due to vacuum polarization only in the pion-Nucleon {Sigma} term suggesting that {Sigma}{sup sea} {approximately} {Sigma}{sup val}. The lattice update is being done on the Connection Machine which is very well suited to simulate QCD with 2 flavors of Wilson fermions (with mass close to the strange quark) using HMCA on 16{sup 3} {times} 32 lattices. 7 refs., 3 figs., 5 tabs.
