OtherSide City Search: enter a city name and it’ll tell you what’s on the exact opposite side of the globe, i.e. where you’d end up if you dig straight down and keep going. Since this site was mentioned on Metafilter, it’s so busy its search script chokes and it gives you an error, but sooner or later you’ll get it to work, I’m sure. This site, jessamyn.com, does pretty much the same thing, and is less busy. Write me if you think you’re the FmH reader closest to the exit from my tunnel starting here in Boston; we can arrange to meet halfway and split the effort, okay?
