Did a deep hole

Remember being a kid and thinking, "If we dig all the straight down through the earth we'll end up in China." Well, thanks to Google Maps and someone being creative, we can now see exactly where you would end up if you dug straight down. From Columbia, SC, we would end up in the Indian Ocean, pretty much due west of Perth, Australia. Find out where you'd be here. This is one of the many "mashups" with Google Maps discussed in a recent NPR interview.

Also, I thought this one from the USA Track & Field website was really cool. It's a jogging distance map, but I could see so many other applications of this one, like an easy way of figuring distance and routes.

Finally, this one looks like a work in progress, but highly valuable for the college student ... beermapping.com.
