Are you concerned about where you go to arrive if you dig a very deep straight infinite hole on Earth? Your problems are solved!
Surf on the map below, choose where you will dig your hole and click there. After this, click on "Dig here!" and you will see the place where, one day, you will (believe me) put your feet.
There's even a mashup for a trip in a straight line around the world.
That app is no good.
My hole I dug when I was a kid went to CHINA!!!!
