Where does Debian store packages on my local disk drive...

["Redefined Horizons" <redefined.horizons@gmail.com>]

I've been using Debian for a few months now, but for the first time
I've got a Debian box hooked to an internet connection. So now I can
finally download Debian packages directly to my work box from the net,
and software installation is much easier! :]

I've got another Debian box at home that isn't wired to the net yet.
I'm wondering if Debian keeps a copy of the packages is autmatically
downloads from the net during software installation, and if so where I
would find the packages. I'd like to snag these, burn them to a CD,
and take them home to my other Debian box. (This will save me the work
of having to download the packages manually.)

Does Debian only download the Debs temorarily, or will I find the debs
for the software installed on my box somewhere in the local file
system?

Thanks,
