Yup. Although you shouldn't hold that against me. ;-)

Do you really need any overly complex map when just showing the
overview? The very first view, that of the entire country, need not be
very complex. You should make liberal and judicious use of MAXSCALE
(or whatever the syntax is... have forgotten most of .map files),
querying and drawing complex geometries only when zoomed in.

Understood. Nevertheless, making the map link upfront and prominent
might be good karma anyway.
