You can make your own version of this map! Here are the steps you will need to take:
  <marker lat="30.349667" lng="-97.754298" title="My apartment" caption="6805 Woodhollow Dr. #320<br/>Austin, TX 78731" address="6805 wood hollow dr." cityZip="austin, tx 78731" tags="|people|daily|family|"/>
    lat and lng can be found from Google Maps.
    Find the spot where you want your marker to show up, double-click on that
    spot to center the map there, and then click on "Link to this page".  The
    URL that shows up will look something like this:
    http://maps.google.com/maps?ll=29.716516,-95.402623&spn=0.004617,0.007685&t=k&hl=en.  Here the value for lat should be
    29.716516 and the value for lng should be -95.402623.title and caption show up on the marker
    and below (the title is the bold part).  If you want to put a line break
    in the caption (which only shows up on the marker), use <br/> (which is irritating, but the XML file has to be properly escaped).address and cityZip are for driving
    directions - if you leave them out, you won't be able to get directions to
    or from the location.tags determine which tags are associated with this
    entry.  Make sure each tag is delimited by | characters (as in the example).If you're having problems, please let me know. To email me, see my home page.
