  There is good evidence that most of the baryons in the Universe are dark and
some evidence that most of the matter in the Universe is nonbaryonic with cold
dark matter (cdm) being a promising possibility. We discuss expectations for
the abundance of baryons and cdm in the halo of our galaxy and locally. We show
that in plausible cdm models the local density of cdm is at least
$10^{-25}\gcmm3$. We also discuss what one can learn about the the local cdm
density from microlensing of stars in the LMC by dark stars in the halo and,
based upon a suite of reasonable two-component halo models, conclude that
microlensing is not a sensitive probe of the local cdm density.
