We all pretty much know about craigslist.com as a free advertising tool
I just found out about another site
they are early in their growth but your post stays there until you delete it.
It's format is obviously a bit different and they actually map the location of the
post in what looks like mapquest.
If you do a search on this site it displays every location on the map for the item you searched for.
Pretty cool
