When I was a kid I would see if I could "dig a hole to China", I think it was a challenge from a parent or grandparent, probably to keep me busy for a while. It now seems ridiculous to think that China was right under my feet, but I didn't know that there was an actual term for this.

In geography, the antipodes of any place on Earth is its antipodal point; that is, the region on the Earth's surface which is directly opposite to it. Two points which are antipodal to one another are connected by a straight line through the center of the Earth. So what is the antipodes of Duluth?

Well, you better have a scuba suit if you're digging a hole straight down from Duluth, because you'll end up in the southern Indian Ocean.  The nearest large land mass is Australia located just over 1,000 miles to the north east of the antipodal point.
