Anyway you want it.
One common thing is:
#set $mylocation = $getVar("location,"unknown")
#if $mylocation == "greensboro"
special stuff
#else $mylocation == "swan-quarter"
different special stuff
#else
something else
#end if
Basically the templates are completely open ended. You could actually
tell the subprofile to use a /different/ template if you really wanted,
though this is not neccessary.
Also, in some cases, you can also take advantage of "Advanced snippets"
to do similar things... they allow you to override snippets based on
profile or system names:

In general, subprofiles are more powerful, though a snippet based
solution may be easier if you are just replacing certain sections of post.
Or you could use the location variable to decide which snippet to
include, etc.
