Query: LMC Microlensing and Very Thick Disks   We investigate the implications of a very thick (scale height 1.5 - 3.0 kpc)
disk population of MACHOs. Such a population represents a reasonable
alternative to standard halo configurations of a lensing population. We find
that very thick disk distributions can lower the lens mass estimate derived
from the microlensing data toward the LMC, although an average lens mass
substantially below $0.3\Msol$ is unlikely. Constraints from direct searches
for such lenses imply very low luminosity objects: thus thick disks do not
solve the microlensing lens problem. We discuss further microlensing
consequences of very thick disk populations, including an increased probability
for parallax events.
