  Last year we proposed using staggered fermions as the light quarks, combined
with nonrelativistic heavy quarks, in simulations of heavy-light mesons. A
first round of tests which focuses on the B_s meson has been completed using
quenched lattices, and results are presented here for the kinetic B_s mass, the
B_s^* - B_s splitting, and f_{B_s}. The next project, already underway, is to
compute the B and B_s decay constants and spectra on the n_f = 2+1 and 3 MILC
lattices. We report on progress with one set of these configurations.
