  We revisit the issue of a correlation between the atomic hydrogen gas in our
local Galaxy and the Cosmic Microwave Background (CMB), a detection of which
has been claimed in some literature. We cross-correlate the 21-cm emission of
Galactic atomic hydrogen as traced by the Leiden/Argentine/Bonn Galactic HI
survey with the 3-year CMB data from the Wilkinson Microwave Anisotropy Probe.
We consider a number of angular scales, masks, and HI velocity slices and find
no statistically significant correlation.
