I got this idea thanks to my clan who's done the same thing. Basically where in the world are you?
Don't put in any precise address, just the city & state/country. Here's the link to view the map:

http://maps.google.com/maps/ms?ie=UTF&msa=0&msid=110368361358206694857.000465808602ac84f3aca

Btw, the map's unlisted so only those who have access to the link can see it.
