Bobby,

The message indicates that the file is already gone. The file is in a 
temporary location, and doesn't survive past the end of the 
Mathematica session.

That location comes from Java, as the value of the java.io.tmpdir 
property. It is a truly bizarre path, but that is a MacOSX-ism. It is 
equally as invisible in the Finder as Mathematica's 
$TemporaryDirectory (/tmp), which is arguably a better choice for 
FetchURL to use. If you don't like the default location, use CopyFile 
after downloading to put it where you want, or, even better, use the 
second argument of FetchURL to pick the location you want.
