All Tiger data for download?

[Gregor Mosheh]

A year or so ago I downloaded the entire TIGER set,
and discovered that the TIGER data doesn't align with
other datasets. (There was a thread on this a month or
three later, that apparently this is a known problem.)

So as long as we're on the topic of grabbing all TIGER
data, I thought I'd re-ask the question of whether the
TIGER data is geographically correct and therefore
usable.
