Don't tell anybody, but I was checking out the Jan. 2008 archives of my blog to see what was going on at this time last year, and came across this link to Strange Maps.
You've got to see this collection of accidental maps (and, uh . . . if you click the link are are greeted with the large heading "Gay Trips to Buenos Aires," just thank Google's oft-embarrassingly erroneous ad-guessing software and scroll down).
