  We calculate the arrival direction distribution of ultra-high-energy cosmic
rays (UHECRs) with a new suite of models of the Galactic magnetic field (GMF),
assuming sources follow the large-scale structure of the Universe. We find a
significantly reduced dipole amplitude compared to previous GMF models, and
trace the change to the accidental position of the peak of the extragalactic
UHECR flux, which falls at the boundary of the strong flux de-magnification due
to the GMF toward the central region of the Galaxy. This serendipitous
sensitivity of UHECR anisotropies to the GMF model will be a powerful probe of
the source distribution as well as Galactic and extragalactic magnetic fields.
Demagnification by the GMF also impacts visibility of some popular source
candidates.
