  We present results of a high statistics study of $f_\pi$, $f_K$, $f_D$,
$f_{D_s}$, and $f_V^{-1}$ in the quenched approximation using Wilson fermions
at $\beta=6.0$ on $32^3 \times 64$ lattices. We find that the various sources
of systematic errors (due to setting the quark masses, renormalization
constant, and lattice scale) are now larger than the statistical errors. Our
best estimates, without extrapolation to the continuum limit, are $f_\pi=134(4)
\MeV$, $f_K =159(3) \MeV$, $f_D = 229(7) \MeV$, $f_{D_s} = 260(4) \MeV$, and
$f_V^{-1}(m_\rho) = 0.33(1)$, where only statistical errors have been shown. We
discuss the extrapolation to the continuum limit by combining our data with
those from other collaborations.
